Description Joachim Reichelt 2005-08-29 06:41:48 UTC

I have:
SCSI aic7xxx (adaptec 2940)
sbp2 devices (Firewire, 2 DISK)
2 swap part /dev/sda2 /dev/sdb2
Suspend does not work.
Test 1.
You must not have 2 swap partitions. swapoff /dev/sdb2 helps
powesave -U:
System seems to stop, but hangs on scsi problems (device not ready)
no poweroff, no resume, a lot of fixes to fs on boot.
Test 2.
If module sbp2 is loaded: Cannot remove sbp2

yes. Almost all SCSI drivers lack proper suspend / resume support, so it will
not work. Unfortunately this won't be fixed for 10.0.

The sbp2 removal failure was because the external disk was still in use and we
refuse to suspend if this is the case - this is a security measure against users
doing stupid things (from a technical point of view ;-) like removing the
external disk while the machine is being suspended. Anyway, even if you removed
sbp2, the system still would not suspend because of the SCSI problem.

Comment 2 Pavel Machek 2005-08-31 19:58:59 UTC

Basically each driver needs suspend/resume handler. There are plenty of
examples, if you feel like fixing aic7xx.

Or if someone can get me aic7xx along with some hardware to test, I may play...

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

Comment 6 Stephan Kulow 2008-06-25 09:52:31 UTC

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 ;(
