Wow, this sounds like this might be the problem. I just checked my `.config' and indeed `CONFIG_APM_ALLOW_INTS' is not enabled. And indeed I have been suspending/resuming the machine a few times before the partition got corrupted.
So, does DMA work correctly on your system after setting this option? I have now disabled it completely as a safety measure (and as suggested by somebody else on this list), and indeed I have not had any more troubles for now. (I have been forcing a fsck every day before turning the machine off.)
Thanks a lot for the hint! I will now rebuild my kernel with that option turned on.
