Hi,

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

[...]

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?

Regards,
Carl-Daniel

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

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.

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

I don't have 'resume' on my command line, but I've CONFIG_..._STD_PARTITION, it works great with 2.6.10 and 2.6.11-rc4:
=====

luca@gismo:~$ cat /proc/cmdline
