[10:51] <sylvainc__> Hello, I have errors booting BTRFS rootfs on Ubunut 16.04 LTS system since linux-image-4.4.0-127-generic update linux-image-4.4.0-124-generic boot without problems, the BTRFS rootfs partition is clean (checked with a livecd), the problem appear mainly on sevral laptop computers, I want to know if you have some pointer about this kind of problem befor I fill a bug report.
[10:51] <sylvainc__> For details I get a kernel panic with error "not syncing: VFS unable to mount root fs on unknown-block(0,0)" when hidden grub boot occurs, but if I enter grub then boot no error occurs.
[10:58] <sylvainc__> I'have done many test with grub reinstall, but linux-image-4.4.0-124-generic boot well in all cases, but linux-image-4.4.0-127-generic doesn't, Thanks for your pointer or help.
[12:15] <apw> sylvainc__, it is not at all clear how the kernel would even know if you hit return or grub did it for you
[12:16] <apw> sylvainc__, i think we need a bug filed, and could you get a 'dpkg -l | grep linux-' output attached to the bug
[12:24] <sylvainc__> apw, thanks for your answer, I agree, it's pretty disturbing, I will try to do some tests before report the bug (if necessary)
[12:25] <apw> sylvainc__, the message implies the kernel is not finding the initramfs which would be grub's fault often
[12:25] <apw> but quite how it does that different for an auto select of 127 as against it picking 127 by default
[12:26] <apw> it beyond me at the moment
[12:32] <sylvainc__> apw, thanks no wories, I will try to find more elements by doing more tests about this issue
[13:22] <cascardo> adding your grub cnfig files to the bug could help
[14:11] <sylvainc__> cascardo, ok thanks i will add it
[14:11] <apw> sylvainc__, and let us know the bug number here in case
[14:35] <sylvainc__> apw, ok, I will continue to work on this issue because I need to understand it, but i must leave now, thanks for your help again
[14:37] <apw> sylvainc__, np
[23:01] <jeremy31> Ubuntu 18.04 killed my bluetooth and it seems that the upstream fix from https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/drivers/bluetooth?id=803cdb8ce584198cd45825822910cac7de6378cb works for everyone
