[Kernel-packages] [Bug 1752961] Re: With kernel 4.13 btrfs scans for devices before all devices have been discovered
I just updated to Debian "4.19.0-0.bpo.1-amd64 #1 SMP Debian
4.19.12-1~bpo9+1 (2018-12-30) x86_64 GNU/Linux"
Even without the "rootdelay" boot option, the boot process proceeds now
as it should again.

[Kernel-packages] [Bug 1752961] Re: With kernel 4.13 btrfs scans for devices before all devices have been discovered
Hi Bogdan!
Sorry to hear, that it doesn´t work for you.
I fear that you did add the parameter in the same way then I did. So there
might be some other difference.
This is my kernel cmdline (cat /proc/cmdline):
BOOT_IMAGE=/vmlinuz-4.18.0-0.bpo.3-amd64
root=UUID=bda00e2f-ad36-46eb-a81a-cceb7736ab65 ro rootflags=subvol=VOL_ROOT
rootdelay=5 apparmor=1 security=apparmor mce=ignore_ce
The apparmor stuff shouldn´t make a difference, it is to my
understanding not started at this early stage. I´m not sure about
mce=ignore_ce. You might give this a try. I can´t remember the specific
issue why I added it, but it was quite likely also related to HP gen8
MircoServer.
Hope this helps you for your further investigations.

[Kernel-packages] [Bug 1752961] Re: With kernel 4.13 btrfs scans for devices before all devices have been discovered
I did my upgrade from Debian stable to stretch-backports and therefore from 4.9
to 4.18 today.
Wrong distribution, I know ;-)
Interestingly, I´m also facing the issue on a HP MicroServer Gen8.
Reason for posting is, that I was able to work around the issue by specifying
"rootdelay=5" at the kernel command line. This might be helpful for others.
Of course, thats just a hotfix and no alternative to solve the real issue.
Exact kernel string (uname -a) is: Linux nas2 4.18.0-0.bpo.1-amd64 #1
SMP Debian 4.18.6-1~bpo9+1 (2018-09-13) x86_64 GNU/Linux
