Description Ulrich Windl 2005-09-06 06:30:52 UTC

After resuming from suspend to disk, the original screen appears but immediately
after that I see a kernel panic. I was able to make a screenshot of the serial
console output (The device I was using did not allow any cut&paste).
Last words of the console are:
Restarting tasks...qinpos = 11, SCB index = 21
Kernel panic - not syncing: Loop 1

Explaining the non-obvious: The system is on a SCSI disk that it connected to an
Adaptec AHA-2940 (Ultra).
Setting up a theory: The controller has its own CPU and RAM. I guess the RAM
contents is lost after power-cycling unless saved and restored. Maybe the kernel
had a different idea what the controller's RAM should contain after resume.

Comment 3 Pavel Machek 2005-09-07 20:12:44 UTC

Well, Adaptec AHA-2940 does not support suspend/resume, I'm afraid. Someone
needs to write suspend/resume methods for it. I do not have hardware available :-(.

Yes. Suspend on SCSI => not supported yet, sorry.

mass reopening all SuSE Linux bugs that are set to REMIND+LATER to change the resolution to WONTFIX (adapting to new policy)

Closing old LATER+REMIND bugs as WONTFIX - if you still plan to work on it, feel free to reopen and set to ASSIGNED.

In case the report saw repeated reopen comments, it's due to bugzilla timing out on the huge request ;(
