Comment # 2 on bug 1233958 from Takashi Iwai

Try to set up kdump and get the crash data if possible.  You might be able to
trigger the kdump via magic sysrq (alt+sysrq+c), too.

Also, since TW is moving already to 6.12.x, please try the kernel in OBS
Kernel:stable repo at first
  https://download.opensuse.org/repositories/Kernel:/stable:/standard/

Once when you get the crash data, please upload.  Otherwise it's tough to debug
without crystal ball.
