That *is* an EIO error reported to the application (translated into
English, that's all).  This generally, but not always, means hardware
problems.

Given that you listed files on your root filesystem getting messed up,
I wonder if syslog/klogd got toasted in such a way that they're still
running (and thus intercepting the kernel console messages) but it's
completely screwed up (so you don't see any kernel messags).

Try booting for a rescue floppy, and then run badblocks on the disk.
If you see media errors reported in that case, then you'll know what's
up.
