I spun up an old machine (with an even older Mylex AcceleRAID card, the
170 w/ a bios dated Jan 21, 2000 - yikes!) recently. While this machine
was running an old 4.7 kernel and booted fine, attempting to update it
to a modern release of Debian with a 6.1 kernel caused the kernel to
hang while booting, with a number of stuck tasks warnings, starting with
udev-worker and including kworker kernel processes.
During troubleshooting, I was able to identify the myrb/myrs drivers
which replaced the old DAC960 driver (removed in commit
6956b956934f10c19eca2a1d44f50a3bee860531) as the culprit. The last
kernel to successfully boot on here is 4.19.x, while anything newer
exhibits the same stuck processes - and indeed, blacklisting the myrb
and myrs drivers allows 6.1 to boot on this machine.
I know this card is functional, as I do have two drives attached to it,
and both it and the drives work fine in 4.19 and older kernels, so the
issue seems to be with the newer myrb/myrs drivers. Is there a chance
of fixing the current drivers, or, at worst, reintroducing the old
deprecated DAC960 driver back into the kernel? I'm not absolutely tied
to using that driver, other than 'it just works' for this card.
Whee, someone is using it!
I'm not alone!
But sure, of course I'll help.
Can you try install openSUSE Leap on it? Then you can open a bugzilla on
our side, and we can track and discuss things there. Debugging via
e-mail tends to be very distracting to others not directly involved.
For starters, a message log might help. And please enable dynamic debug
via
echo 'file drivers/scsi/myrs.c +p' > \
/sys/kernel/debug/dynamic_debug/control
echo 'file drivers/scsi/myrb.c +p' > \
/sys/kernel/debug/dynamic_debug/control
Cheers,
Hannes
