Which kernel do you have?

I don't know if it is related, but today I upgraded from
linux-image-2.6.15-20 to linux-image-2.6.15-21 and the new kernel also
crashed when resuming from STR. I can't even produce a log because it
complains about my ext3 partition and remount it read-only. So the
only log I have is a text screen of 80x25 characters :-(

To be sure, I booted again with the previous kernel and it worked
again. Well - at least, as badly as before: I already mentioned the
problem on the kubuntu-devel list... During the first resume from STR,
I have 3 times a message about a "problem with the ATA thingy" which
delays the resume for maybe 15s. Then all following resume are

In the changelog of the kernel, it is written that they improved the
ACPI part... not so sure ;-)
