Public bug reported: 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. ----------------->%----------------- Jan 20 08:54:23 Ubuntu-1804-bionic-64-minimal kernel: megaraid_sas 0000:18:00.0: Failed to register IRQ for vector 64.
