Comment # 6 on bug 1195857 from Sergey Mashkov

Sorry for delay, had to work more at my main job. 

The picgture actually has changed. Unfortunately, the older kernel (5.16.2-1)
may also fail to suspend with the same error but it only hapens after few days
and usually works perfect. With never kernels it never works even after
reboot/first boot. 

The other issue I've faced is that I use secure boot and I don't get how to I
make a key and piblish it to the keystore so my custom kernel may boot. I
haven't compiled kernels almost about 10 years so could you please point me to
some guide how do I set it up properly?
