Subjectively I have relatively long pause after first Suspending = console message (where it hangs otherwise), according to dmesg timestamp it is about 1 second before next messages appear. Also last two times I tried it writeo= ut of suspend image was really slow; it was both with and without battery. Rea= ding on resume in really in order of magnitude faster. But manual STD so far works both on AC (with or without battery) or on batt= ery. Of course it is possible that battery gets exhausted during STD, but system is not switched off. Rather I would suspect something like ACPI notification that comes during freeze ... If someone can advice which options to enable I could try netconsole. But l= ikely not before next weekend. --nextPart2192903.YP4mebRK1D Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (GNU/Linux) iD8DBQBHN05zR6LMutpd94wRAvFtAKCoMHdzTogdmFjJxHgtBoFxEmjS0ACffNe3 1vxYlpP5TBURN+3w2N04Us8= =bOEK -----END PGP SIGNATURE----- --nextPart2192903.YP4mebRK1D--
