[02:02] <fabbione> BenC: ping?
[02:02] <BenC> fabbione: yo
[02:03] <fabbione> BenC: hey man.. i think something on i386 kernels is broken badly
[02:03] <BenC> fabbione: Can you describe?
[02:03] <fabbione> trace -o /home/fabbione/foo.strace /bin/ls
[02:03] <fabbione> umovestr: Input/output error
[02:03] <fabbione> bin    dev   initrd      lib64       mirrors  proc  sbin  tmp  vmlinuz
[02:03] <fabbione> boot   etc   initrd.img  lost+found  mnt      raid  srv   usr
[02:03] <fabbione> cdrom  home  lib         media       opt      root  sys   var
[02:04] <fabbione> make that a strace
[02:04] <fabbione> i get a lot of errors (also confirmed by different people on #u-devel) like that umovestr
[02:04] <fabbione> it seems to happen only i386
[02:04] <BenC> is this the -12 kernel?
[02:05] <fabbione> if you strace something bigger you might see also other errors like ptrace: Input/Output error
[02:05] <fabbione> confirmed to be there from at least .20-9
[02:05] <fabbione> but yes. i am specifically running .20-12
[02:05] <BenC> hmm
[02:11] <BenC> cool, I have -6 and -7 on this box, let me check those
[02:12] <fabbione> ok
[02:19] <BenC> fabbione: Same on -7
[02:19] <fabbione> ok
[02:29] <Keybuk> BenC: random question about the kernel, if you have time to answer it
[02:30] <BenC> Keybuk: Sure
[02:30] <Keybuk> disk write cache; does that get flushed on shutdown?
[02:30] <Keybuk> specifically for IDE
[02:30] <mjg59> Yes
[02:31] <Keybuk> can you cite a reference in the source; I couldn't find out for definite where it happened
[02:31] <mjg59> Unless you're seeing massive filesystem corruption, in which case the answer is probably no (but shouldb be yes)
[02:31] <Keybuk> I can see it happens when you reboot, but not halt or poweroff
[02:31] <Mithrandir> hm, maybe that's the reason why I've seen some ext3 corruption in the past.
[02:32] <mjg59> Keybuk: Hm. In the poweroff case, I suspect that it's supposed to be done when the drive's powered down
[02:32] <Keybuk> but I can't see anything that even powers down the drive :p
[02:33] <mjg59> Keybuk: Just to clarify - do you mean drivers/ide or libata?
[02:33] <BenC> fabbione: Same as far back as -6
[02:33] <Keybuk> drivers/ide
[02:34] <Keybuk> reason for asking:
[02:34] <Keybuk> the sysvinit halt binary deliberately standbys IDE disks by iterating /proc/ide
[02:34] <Keybuk> and the manpage claims this is because the Linux kernel doesn't
[02:34] <mjg59> Hm. It's conceivable.
[02:34] <Keybuk> this seems somewhat silly to me; and causes problems when you try and run halt on things like <hardware from Sony>s which don't have an IDE controller
[02:34] <mjg59> (Go go stupid workarounds)
[02:35] <Keybuk> I could believe that the manpage is way out of date
[02:35] <Keybuk> or if not, and it's a simple patch, it'd seem sweeter to fix the kernel?
[02:35] <mjg59> Yeah
=== seb128 [n=seb128@ubuntu/member/seb128]  has joined #ubuntu-kernel
[02:50] <ivoks> mjg59: do we have any policy for 
[02:50] <ivoks> mjg59: doh.. STOP_SERVICES in /etc/default/acpi-support
[02:50] <mjg59> Yes. Don't add things to it.
[02:51] <ivoks> ok :)
[02:51] <kylem> Keybuk, are you complaining about what? sata/scsi?
[02:51] <mjg59> kylem: drivers/ide
[02:52] <kylem> ah.
[02:52] <kylem> well. turn off your write cache. it's a bad idea anyway.
[02:52] <Keybuk> kylem: is it off by default? :p
[02:52] <kylem> it should be on most disks.
[02:53] <kylem> unless hdd folks have gotten really ballsy in the last couple years.
[02:54] <kylem> SCSI device sda: write cache: enabled, read cache: enabled, doesn't support DPO or FUA
[02:54] <kylem> huh. poop.
[02:54] <Keybuk>        The  -h  flag  puts  all  harddisks in standby mode just before halt or
[02:54] <Keybuk>        poweroff. Right now this is only implemented for  IDE  drives.  A  side
[02:54] <Keybuk>        effect  of putting the drive in standby mode is that the write cache on
[02:54] <Keybuk>        the disk is flushed. This is important for IDE drives, since the kernel
[02:54] <Keybuk>        doesnt flush the write-cache itself before poweroff.
[02:54] <Keybuk> (is the sysvinit halt manpage reference)
[02:54] <kylem> anyway, if you're using libata-pata, the scsi layer will send a SYNC CACHES command which should end up in libata and be issues properly to the drive.
[02:55] <kylem> Keybuk, interesting.

[04:22] <seb128> hi
[04:23] <seb128> I'm trying to rebuild a feisty kernel with the 8390.c from edgy following the instructions on https://wiki.ubuntu.com/KernelCustomBuild
[04:23] <seb128> I've apt-get install linux-source, copied the tar.bz2 somewhere, untar-ed it, copied the .c and now I'm running "AUTOBUILD=1 fakeroot debian/rules binary-debs" which doesn't work
[04:24] <seb128> "make: *** No rule to make target `binary-debs'.  Stop."
[04:24] <seb128> any idea of what I'm doing wrong? ;)

[04:33] <seb128> thank you
[04:33] <abogani> seb128: Nothing
[04:35] <Simira> does anyone know the bug number on "fan doesn't work after resume"? It's a kernel bug with hp laptops, that's reappeared. 
[04:38] <BenC> Simira: It should be fixed in 2.6.20-12 kernels
[04:43] <Simira> BenC: I just tested on daily
[04:43] <Simira> BenC: and it doesn't work for me
[04:43] <BenC> Does it have -12 kernel?
[04:43] <Simira> yup
[04:44] <BenC> I included all the mentioned patch sets to fix that, so if something else is needed, someone with that hw will have to work out what it is
[04:44] <BenC> You've got about 3 weeks to do it :)
[04:45] <Simira> I'll test again. We're two testing this spesific model, so we should manage to work it out
[04:46] <BenC> Simira: If you need to find the bug, do an advanced search on linux-source-2.6.20 and include "Fix Released" bugs
[04:46] <Simira> BenC: I'll do that. Thanks
[04:49] <seb128> anything else I can try about bug #87078? 2.6.20 doesn't build with the 8390.c from 2.6.17
