Public bug reported:
Dear developers,
My system freezes whenever I try to 1) shutdown, 2) restart, or 3) suspend it.
System gets unresponsive (keyborad, mouse, network - ssh/ping from
outside), screen turns black. However, non of the actions 1-3 gets
finished, i.e. my system does not turn off, restart, or sleep. Hw reset
needed after it.
It is always reproducible and happens for kernels linux-image-5.11.0-41-generic
and later.
Does not happen for kernels linux-image-5.11.0-40-generic and earlier.
Corresponding Journal sections (5.11.0-40 & 5.11.0-46) attached.
Any other information or test you need, please let me know.
Thank you!
