Title:
HP Smart Array driver fails to load, kernel panics boot process
Status in linux package in Ubuntu:
Confirmed
Bug description:
Hi
I have an HP ProLiant G6 with a Smart Array controller on Bionic,
Kernel 4.15.0-15, that fails to load the hpsa driver for the Smart
Array, (occasionally) drops to the initramfs shell, as it cannot find
a root device in a reasonable amount of time, and then finally kernel
panics with the stack trace leading to the hpsa driver. Occasionally
it will complain about resetting the logical volume scsi bus.
Downgrading to the previous kernel 4.15.0-13 works just fine.
Attached is a screenshot showing the kernel panic, and below is a link
to a YouTube video of the whole boot process, a video recording from
ILO. To save you the time of watching the whole thing, 39 seconds is
the bus reset error, then it hangs around waiting for a root device,
and the kernel panics at 4:16. The relevant information are separate
below
