--- Comment #6 from Hans de Goede (jwrdego...@fedoraproject.org) ---
Thank you for reporting this and sorry about the regression.

So you have build your own 6.6.17 kernel from source with just that commit
reverted and with that locally build 6.617 with that single commit reverted you
are not seeing this issue ?

I just tried to reproduce this on one of my own laptops with a Apollo Lake
N3450 processor, but I cannot reproduce this. So this seems to be specific to
this one laptop model.

Unfortunately that is incomplete due to the errors being spammed to the log the
entire time, so it only contains a long list of the errors repeating.

Can you append " log_buf_len=50M" to your kernel commandline and then
*immediately*after boot run "dmesg > dmesg.txt"?  And then please attach the
generated dmesg.txt here in bugzilla using bugzilla's attachment function.

Using pastebins is problematic because the links to these become invalid over
time.
