Bug Description

It appears that in recent Kernel versions the megaraid_sas cannot properly handle suspend to RAM (rtcwake -m mem -s 30).

After the system wakes up, the megaraid_sas driver reports multiple errors and I/O to disks fails completely. A reset is required to make the machine work again.

The issue appears to be fixed in Mainline Kernel 5.6.6.

So far, I have not done further research, when this fix was implemented excatly. If needed, I can do further mainline or -rc tests.
