Subject: bug#58914: linux-libre kernel socft-lock on T400 Thinkpad (BTRFS related?)
Date: Mon, 31 Oct 2022 02:14:16 +0100

The latest kernel reliably soft locks on my T400 thinkpad.  Sometimes it
locks up before the elogind login prompt, sometimes it reaches the
prompt but I can't log in.  It does not reboot on ctrl-alt-del, although
it does seem to send some kind of signal to elogind.  It does reboot for
alt-sysrq-b.
When I got to see the kernel log, it looked like it was stuck in some
BTRFS related code.  I use BTRFS on an SSD on this machine.
I know we have some other users with T400 Thinkpads, maybe they have run
into it as well?

I will try upgrading again since the kernel is a few days old.
