media problems.

I'm not so sure, at least in my case. Sure, badblocks /dev/hda1 reports an
access beyond end, but neither badblocks /dev/hda1 $SIZEOF_HDA1 nor SMART
do. Anyway, the alleged bad blocks are at the end of a 400 MB partition, so
unless swsusp allocated swap randomly, there's hardly any chance I could
hit them with 256 MB RAM and LZF on. But then, this failure was a single
event in my case, while others reported some regularity.
Best regards,

Badblocks error reading beyond the end of the partition is irrelevant,
it is a primitive bug somewhere unrelated to media condition.

Also Badblocks without disabling drive cache is _utterly_useless_.

It will not be a bare swsusp bug, I would have hit that in 20K+ cycles
since using LZF and a thousand or so of other 2.4 users would have
hit it too.

Please help indentify the actual problem by running some decent tests.
