LimCorehello, I have some problems with using 1 TB hard drive.  my hard drive still fails...  sata link dies, any ideas? https://bugs.launchpad.net/ubuntu/+source/linux-meta/+bug/40963902:16

Q-FUNKogasawara: morning!  was there anything else I should test for this kernel panic bug?08:02

ubot3Malone bug 396286 in linux "2.6.31-generic: kernel panic near the end of initramfs" [High,In progress] https://launchpad.net/bugs/39628608:07
bfoxAfter upgrading to the latest Karmic kernel (2.6.31-5-generic), Function-F4 no longer suspends my ThinkPad.  Known bug?09:24
bryceapw, btw I've got the userspace stuff for ati kms together into a ppa:  https://edge.launchpad.net/~ubuntu-x-swat/+archive/kms10:34
bryceapw, we're thinking of putting it on a usb stick and passing it around for testing10:34
bryceapw, would you like a kernel included on that?10:34
bryceapw, we can stick 2.6.31-4.22kms2 on it, if you think that's more worth testing than the current kernel10:36

dinh_fslhi amitk16:19
dinh_fslamitk i have a quick question for you...16:19
manjodinh_fsl, amitk shoot16:23
manjodinh_fsl, what is ur q ?16:24
dinh_fslon 2.6.31...it looks like usb autosuspend is enabled for the USB HID driver correct?16:24
amitkdinh_fsl: what tree and branch are you looking at?16:27
dinh_fslmanjo: amitk/mx51-port-2.6.31.git16:27
manjodinh_fsl, is this a generic q about 2.6.31 or is it wrt amitk tree ? 16:27
dinh_fslmanjo just a generic question regarding 2.6.31...16:28
dinh_fslmanjo this is just generic hid and usb hid driver code in the linux kernel16:28
manjodinh_fsl, # USB Input Devices16:29
manjo#16:29
manjoCONFIG_USB_HID=m16:29
manjoCONFIG_HID_PID=y16:29
manjoCONFIG_USB_HIDDEV=y16:29
manjoso I dont see any suspend enabled in the config ...16:29
manjoah16:30
manjoshit 16:30
manjoCONFIG_USB_SUSPEND=y16:30
manjodinh_fsl, amitk ^^16:30
dinh_fslmanjo no no...in /driver/hid/usbhid/hid-core.c, there are alot of changes that will allow a hid device to suspend...16:30
manjodinh_fsl, yeah it is enabled in the karmic 2.6.31 tree16:30
manjodinh_fsl, but nothing like USB_HID_SUSPEND... 16:31
manjodinh_fsl, auto suspend is enabled by default16:32
amitkdinh_fsl: USB_SUSPEND is not enabled by default16:33
amitkdinh_fsl: do you need it? I can enable it on the imx51 branch16:34
manjodinh_fsl, oops.. I gave you wrong info amitk is  has the correct info16:34
dinh_fslmanjo : let me clarify...it looks like on 2.6.28, a usb device such as a mouse(HID) can autosuspend, but it cannot if the device is opened...16:34
manjodinh_fsl, I was looking at .config which was the wrong config 16:34
dinh_fslmanjo amitk but it appears on 2.6.31, a usb hid device can be autosuspended even when it is opened...just want to know if you guys can confirm that16:35
manjodinh_fsl, are you using ubuntu source tree ? 16:36
dinh_fslmanjo  it doesn't matter if its ubuntu or not...just the linux kernel hid driver...16:37
manjodinh_fsl, I guess I dont know the ans to that16:40
manjodinh_fsl, as far as configs are concered I see arch/x86/configs enabled x86_64_defconfig:CONFIG_USB_SUSPEND=y16:41
manjobu ubuntu configs turns off auto suspend, these configs are in debian/config16:41
manjodinh_fsl, not sure if that ans helps you16:42
dinh_fslmanjo yeah, i know...there are alot issues around autosuspend so I understand why ubuntu is doing that...but as a superuser in Ubuntu, I can bypass that, but it still won't autosuspend...16:44
dinh_fslmanjo I just saw threads about 2.6.30 + enabling this features at a driver level...16:45
* ogra waves16:48
amitkdinh_fsl: autosuspend has been plagued by many problems since it was introduced circa 2.6.28. Most USB peripherals don't deal with usb suspend nicely. Upstream enabled it my default in 2.6.28, then disabled it. I've not kept up with the current state16:48
amitk*by16:49
dinh_fslamitk that's what i thought...i see some fixes/changes in 2.6.31 and want to test it out...16:50
amitkdinh_fsl: you know the sysfs files to grok autosuspend?16:52
dinh_fslamitk for usb devices   its /sys/bus/usb/devices/*/power/level16:53
amitkright16:53
dyfetdinh_fsl: I have a question about ethernet line sensing...16:53
dinh_fslhi dyfet16:53
dinh_fsldyfet its not in my area of expertise, but want to see what your status is on that issue...16:54
dyfetdinh_fsl: hi, my problem is that when I plug in a cable connected to some switches, the board immediately turns off...16:54
dinh_fsldyfet did you see my email with recommendations on turning off a couple of kconfig options?16:55
dyfetdinh_fsl: no I did not16:55
ogradinh_fsl, it happend even before a kernel is loaded16:55
dinh_fsldyfet we've been trying to recreate the issue here, but can't do it yet...16:55
ogra*happens16:55
dinh_fsldyfet only on some switches?16:56
ograif the situation is there the board doesnt power on either until you unplug the ethernet cable16:56
ograwe currently only have netgear switches around16:56
dinh_fslogra so even running in uboot or redboot, it will power off16:57
dinh_fsl?16:57
ograyes16:57
ograand wont power on again16:57
ograuntil you pull the plug16:57
dyfetdinh_fsl: until the cable is removed16:57
dyfetdinh_fsl: if you poweron with the cable plugged in, it powers back off immediately....16:57
dinh_fsldyfet how many bbg2.5 board do you have? it happens on all the boards? 16:58
ogradinh_fsl, we have 1016:58
ogra3 here on site atm16:59
ograi didnt see that behavior with the board i have at home 16:59
ograone of the switches here is identical with the one my board at home is attached to16:59
dyfetdinh_fsl: the b2.5 board I have at home I never encountered this.  The board I have here and the one ogra has here does this.16:59
dinh_fsldyfet how many boards have you seen this problem on? I think we need to get that board in house to debug.17:00
ograall three we have here 17:01
dyfetyep17:01
ograwe measured a bit and it seems the issue hapens as soon as the voltage on the signal line of the ethernet cable raises a bit17:01
ogra*happens17:01
dinh_fslogra dyfet can you please give manoj a board that has this problem? I can get it from him to debug next week...17:03
ograwe have one paticular AP/wireless bridge, that raises the overal voltage by 0.5V it is very easy to reliably reproduce the issue by plugging it into the switch17:03
ogra*overall17:03
dinh_fslogra dyfet sounds like a HW, board issue...please give the bad board to manoj and he can give it me next week to debug...17:06
ogradinh_fsl, ok, sorry, that took a moment to clearify here since all boards are fixed planned for development work from monday on 17:08
ogradinh_fsl, we'll get manjo one of the boards though17:09
manjoogra, ack17:09
dinh_fslogra dyfet i'm off to chicago next week...so I won't be able to get it from manoj til the following week...anybody going to be in chicago next week?17:11
dyfetdinh_fsl: I think ogra is checking about this...17:15
ogradinh_fsl, i dont think anyone of us is in chicago next week, but the issue is easy to work around by using a USB NIC so it wont block us 17:19
ograread: from our side it can wait a week until you can get to it17:19
dinh_fslogra dyfet ok great...17:28

CaMasonhi guys. My rt2860 wifi can't connect using any kernels above 2.6.28-11. I've been told I should come here and report it18:52
CaMasonin the working kernel, modinfo shows the path is working is kernel/updates/dkms/rt2860sta.ko, broken is kernel/drivers/staging/rt2860/rt2860sta.ko18:53

mau__i would like to compile the kernel23:21
mau__what do you think??23:26
TheMusomau__: If everything is working, why do you need to compile the kernel?23:29
TheMusomau__: In addition, I think the people who are in the best position to help you are currently unavailable at the moment.23:29
mau__i just want to learn23:36
mau__and if posible make things better23:37
