I reported this one as - you said, its an TuxOnIce bug: https://bugzilla.kernel.org/show_bug.cgi?id=15873 I switched compression on my ThinkPad T23 where it happened all 2-4 days or so with 2.6.34 from LZO to LZF. And since then I didn't get the error anymore, but with only 5 attempts so far, so I am not sure whether switching to LZF "fixed" it: deepdance:~> cat /sys/power/tuxonice/debug_info TuxOnIce debugging info: - TuxOnIce core : 3.1.1.1 - Kernel Version : 2.6.34.1-tp23-toi-3.1.1.1-04990-g3a7d1f4 - Compiler vers. : 4.4 - Attempt number : 5 - Parameters : 0 667656 0 1 0 0 - Overall expected compression percentage: 0. - Checksum method is 'md4'. 0 pages resaved in atomic copy. - Compressor is 'lzf'.

Maybe its a good idea to collect information in that bug report, even when it really is a TuxOnIce one.
