| djs | is there any reason the new 4.7.0 mainline kernel would not want to decrypt the rootfs on boot? | 00:08 |
|---|---|---|
| djs | tried upgrading today but my disk is encrypted and 4.7.0 doesn't ask for a passphrase | 00:09 |
| djs | ubuntu 14.04 | 00:09 |
| apw | djs, no known reason, the configs for those are generated from what is nearest so things can get lost | 07:55 |
| apw | they are only test builds | 07:55 |
| sforshee | smb: do you know if we still have utilities expecting xenbus to be mounted at /proc/xen? | 12:49 |
| smb | sforshee, yeah I was asked the same just a couple of minutes ago | 12:49 |
| sforshee | smb: oh, hah, I'm sure it's the same issue | 12:50 |
| smb | its those xe-guest-utilities which mount it so the guest can fill some guest data into the xenstore of the host | 12:50 |
| sforshee | smb: I just noted that there's a CONFIG_XEN_COMPAT_XENFS option which controls whether /proc/xen is created, and notes that it's for "old xenstore" tools | 12:51 |
| smb | sforshee, I had a look into the startup script of dom0 and those still want /proc/xen. So I have afeeling its less legacy than it sounds | 12:56 |
| sforshee | smb: ack, thanks | 12:58 |

| xboy | Hi there! | 17:15 |
| * apw looks up | 17:15 | |
| xboy | I was wondering if ubuntu 16.10 going to have the kernel 4.6 or above ? | 17:15 |
| apw | xboy, yes, we have a 4.6 kernel pending now, which i hope to release when the freeze lifts for alpha2, 4.7 is being prepared | 17:16 |
| xboy | great! | 17:16 |
| xboy | I'm having trouble installing ubuntu 16.04 in a lenovo yoga 900, because of the nvme ssd, apw do you know if the kernel 4.6 have a good support for that kind of ssd? | 17:18 |
| apw | xboy, depends what sort of nvme disk it is, i have heard peopel saying nvme "version 2" disks are a problem but i have not seen any evidence | 17:20 |
| apw | xboy, does the disk even get recognised ? | 17:20 |
| xboy | no, during installation process(live usb) the system does not recognize the disk | 17:25 |
| apw | xboy, how are you determining that, not offering a disk to install to ? | 17:25 |
| apw | if you boot "Try Ubuntu" on it, and open a terminal, is the disk mentioned at all in dmesg | 17:26 |
| xboy | apw it's a samsung mzvlv512hcjh | 17:26 |
| apw | i can have a look at the dmesg if you can pastebinit or similar | 17:26 |
| xboy | give a sec. going to see dmesg | 17:26 |
| apw | xboy, and indeed what does "sudo lswh -c disk" say | 17:28 |
| xboy | ok, going to check | 17:29 |
| xboy | almost ready | 17:41 |
| xboy | here it's apw http://paste.ubuntu.com/21167215/ | 17:46 |
| xboy | dmesg output | 17:46 |
| xboy | apw http://paste.ubuntu.com/21167520/ for the lshw command | 17:48 |
| apw | xboy, and if you "sudo modprobe nvme" does anything appear in the bottom of dmesg / | 17:49 |
| xboy | no, nothing apw | 17:50 |
| xboy | do you know what can I do so the system can detect it? | 17:55 |
| apw | xboy, at this moment, no. | 17:55 |
| xboy | do you know if the kernel 4.6 or 4.7 can help me apw? | 17:57 |
| apw | xboy, i do not | 17:57 |
| xboy | thank you apw! | 17:57 |
| xboy | oh one more question apw, do you know who can help me? | 17:58 |
| apw | xboy, from what i can see you are not the only one complaining, and the issue seems to affect linux in gneeral | 17:59 |
| apw | there is some discussion out there that suggests there may be something in bios, but not what | 17:59 |
| xboy | ohh ok, I'm going to try to talk to samsung | 18:02 |
| xboy | or where can I find a ubuntu live usb with a newer kernel(maybe that helps)? | 18:03 |
| apw | there is no installer image yet with a newer kernel, there may well be by next week, but not now | 18:04 |
| xboy | will wait then, thanks! | 18:06 |
| apw | xboy, i believe there is some work looking into this going on somewhere, i just do not know who right now | 18:06 |
| xboy | ok great, any idea where can I search? | 18:09 |
| apw | this was something i heard spoken about ... | 18:12 |
| xboy | oh ok | 18:13 |
| apw | ogra_, which package were you seeing us pointing to /GPL ? i have looked over the primary kernels and they all point to /GPL-2 | 21:53 |
| ogra_ | apw, meta | 21:54 |
| ogra_ | iirc | 21:54 |
| xboy | Are you there apw? | 21:54 |
| apw | ogra_, ahh yes, ok, thanks | 21:54 |
| xboy | If I download the latest kernel from ubuntu mainline, where I can find the vmlinuz and initrd.lz? | 21:55 |
| apw | xboy, the vmlinuz is in the linux-image-* the initrd is made when installed | 21:59 |
| xboy | ok thanks | 22:01 |
| attente | hi, how do i pass -no-pie when building the kernel? is there some env var i should set? | 22:31 |
| djs | apw: any ideas on how I might debug the 4.7.0 mainline kernel's failure to ask for a passphrase to decrypt the rootfs on boot? | 23:01 |
| djs | I assume the problem is in the initrd or initramfs-tools somewhere | 23:02 |
