Package: uswsusp
Version: 1.0-1
Severity: normal
Recently (after a kernel upgrade?) s2disk stopped working. I get:
| [bas@helena]~> sudo s2disk
| s2disk: Could not use the resume device (try swapon -a). Reason: Invalid
argument
Swap is active and on a normal partition (/dev/sda12):
| [bas@helena]~> swapon -s
| Filename Type Size Used Priority
| /dev/sda12 partition 2048252 42436 -1
strace shows:
| [bas@helena]~> sudo strace s2disk
| execve("/usr/sbin/s2disk", ["s2disk"], [/* 23 vars */]) = 0

That is, the ioctl SNAPSHOT_SET_SWAP_AREA in set_swap_file() in
suspend.c fails. Looking at the kernel souces, this only return
EINVAL if the block device that is passed (maj 8, min 12) cannot be
converted to its kernel-space representation.
ANy idea what's hapeing here?
