Comment # 1 on bug 1231262 from Takashi Iwai

Is this a regression in the recent Leap 15.6 update, or it's persistent in the
older Leap 15.6 kernel, too?  You can try to install the older 6.4 kernel (with
--oldpackage option of zypper install) and check whether it shows the same.

If it's persistent, could you check the recent upstream kernel from OBS
Kernel:stable:Backport repo, and see whether the problem happens or not?

Last but not least, please give the full dmesg output and hwinfo output from
the problematic kernel.  Use attachments on Bugzilla.
