[tboot-devel] suspend problem since kernel 5.15

[Derek D. <z2...@po...>]

I am using tboot 1.10.3 and all was working fine with Linux kernel
5.10.88. However, I upgraded to kernel 5.15.16 and, while booting seems
to happen properly, suspend is broken. I am using a Lenovo T460p.
Usually when suspending the power button LED will blink 8 times and then
it goes into a sleep state. With the newer kernel I get power LED and
caps lock LED blinking, cpu fan runs fast, and can't get out of that
state. Need to hard powerdown.

Attaching a txt-stat output. Any ideas what may be happening? Seems like
I maybe need to report to the kernel devs, but let me know if you have
some other suggestions. I could do a git bisect of the kernel source and
probably find the kernel code changes that broke suspend for me. Please
advise

Thank you,
Derek
