swsusp fails with "FATAL: cannot find swap device, try swapon -a!"

swsusp fails with "FATAL: cannot find swap device, try swapon -a!"

[Carl-Daniel Hailfinger]

Hi,

since 2.6.10-rcsomething (don't know exact revision), suspend-to-disk
fails on my machine. dmesg excerpt:

[...]
Adding 530104k swap on /dev/hda6.  Priority:42 extents:1
[...]
PM: suspend-to-disk mode set to 'shutdown'
Stopping tasks: ===================================================|

And I have absolutely no idea what's going wrong. Kernel is vanilla
bk tree from 10 days ago. .config is similar to SUSE .config, but I
left out some drivers I don't need.

Any idea what could be wrong with my setup?

And you have resume= on command line, right? CONFIG_..._STD_PARTITION
should not be required, but I have it set like this:

pavel@amd:~$ cat /proc/cmdline
root=/dev/hda4 resume=/dev/hda1 psmouse.psmouse_proto=imps psmouse_proto=imps psmouse.proto=imps
pavel@amd:~$ grep hda1 /usr/src/linux/.config
CONFIG_PM_STD_PARTITION="/dev/hda1"
pavel@amd:~$

And CONFIG_PM_STD_PARTITION was not set. I'll retry with it being set

Setting CONFIG_PM_STD_PARTITION didn't help at all. Still the same
message on suspend-to-disk with current -bk tree.

So resume_file has a non-zero length, but resume_device is 0:0.
How can that happen?

That's no such device. Do you have ide support built as modules and
loaded from an initrd?

Yes.
CONFIG_IDE=m
CONFIG_BLK_DEV_IDE=m

Pavel, could you add a warning to the code which is a bit more
obvious? "Cannot find swap device" on suspend is a little bit
confusing. How about "No swap device available at resume time"?

Catching error -6 and telling user that suspend will not work because
it would not be able to resume, anyway, is probably way to go. Feel
free to suggest a patch ;-).

Hi,

A friend pointed me to this list. I came to the same conclusion:

http://marc.theaimsgroup.com/?t=110789542400001&r=1&w=2

I will now see if 2.6.11-rcX fix this.
