[Yusuf Talha via Bug reports for GNU Guix]

i used linux-libre-5.10 and it worked fine.  but today i've tried 
linux-libre-5.12.7 and it seems like the problem has solved.  thanks for your 
help.

I've started a meta-discussion that is related to this issue:

Mark, it would be great to hear your opinion on it.

FYI, linux-libre 5.12.4 also locked up on my Thinkpad X200, within a
minute of launching an Xorg session, and within a couple of minutes of
booting.  I only tried booting into that kernel once, and I didn't try
any other 5.12.x series kernel.

For now, I've switched to the 5.10.x series.  5.10.39 and 5.10.40 have
been working well for me.

Thanks for the report.

  Mark

Sorry to hear that.

The first step to solving this the "Guix way" is to rollback your
system, using the `guix system` command [0].

For example, you could use `guix system list-generations` to find the
most recent generation of your system profile that does not use
linux-libre 5.12. Then, you would use `guix system switch-generation $N
&& reboot`, where $N is the number of the generation you'd like to roll
back to.

Once your system is working again, I recommend choosing the 5.10 kernel
series, by putting (kernel linux-libre-5.10) in your config.scm [1],
reconfiguring, and rebooting. 5.11 is no longer available.

The 5.10 kernel series will be supported upstream until the end of 2026
[2], and hopefully will not introduce regressions for your hardware.

Finally, you may search for upstream bug reports, or report the bug to
Linux. I doubt many kernel developers are testing on the x200 at this
point, so they will need bug reports in order to fix the problem.

I hope that helps.

Maybe your computer is experiencing an OOM (out-of-memory).

Maybe keep a system monitor visible (e.g. gnome-system-monitor or htop)
and keep an eye on the memory & swap usage. Does the freeze coincide with
high memory usage?

Also, can you still hear your disk spinning after a freeze?
(IIUC, that would indicate Linux is still issuing I/O to the disk
so Linux did not OOP? I'm not an expert on these matters though.)

What was the latest kernel version that worked for you?

Greetings,
Maxime.

hello.  i am using a librebooted thinkpad x200 laptop with gnu guix.  if i use 
the latest kernel on my system, my computer suddenly freezes without a reason 
after a while of usage.  it is probably a kernel panic.  older kernels don't 
have that problem.  i'd be glad if you fix this.  thank you for your attention.
