Package: uswsusp
Version: 0.2-1
Severity: important
Two of the three swsusp methods fail, and segfault when attempting to
read the configuration file. The configuration file was created with
dpkg-reconfigure, and contains:
# /etc/uswsusp.conf(8) -- Configuration file for s2disk/s2both
resume device = /dev/sda1
compress = y
early writeout = y
checksum = y
Regarding the other bug listed, I've tried it as both "resume device"
and "resume_device" but it seems to make no difference as far as the
segfault issue goes, although removing everything but "resume device"
does allow the system to hang at "Snapshotting system" instead of just
segfaulting. :)
I am attaching an strace of the problem. Please note that it makes no
different if run as root, or under sudo; the problem remains the same.
It is worth noting that s2ram does not segfault, although it has other
issues which aren't relevent to this particular bug.
Here is the strace:

Also, here are some interesting factoids from the s2disk/s2ram -n flags:
$ sudo s2disk -n
suspend: Could not stat the resume device file
$ sudo s2ram -n
Machine matched entry 182:

Fixes: 0x2c VBE_SAVE VBE_POST
Machine is in the whitelist but perhaps using vbetool unnecessarily.
Please try to find minimal options.
This machine can be identified by:
sys_vendor = "IBM"
sys_product = "25285FU"
sys_version = "ThinkPad X41"
bios_version = "74ET48WW (1.17a)"

Hope this all helps. :)
