The following messages appear visible during boot:

When booting the kernel 5.15.0-48, the messages just appear. When
booting a newer kernel, these messages still can be seen but nothing
happens afterwards.

Title:
Thinkpad P14s A 2nd Generation: No boot with Kernel > 5.15.0-48
Status in linux package in Ubuntu:
Confirmed
Bug description:
Hello,
I use Kubuntu 22.04 LTS on my Lenovo P14s (21A0-0000GE). After updating the
Kernel to a version above 5.15.0-48, the system didn't start. I therefore used
the old one (Version 5.15.0-48) from the recovery menu - the machine boots
again.
I believe that this information is not enough to assess the problem. I
see some error messages even when the machine boots correctly. Could
anyone please tell me what I should try out or read out to get more
information?
Many thanks,
Felix
