The sysrq-e output is probably just standard ext3 journalling unrelated to
the problem... what does dmesg say? lspci? What's your hardware setup?
dmesg ; smartd ; dmesg yields no new entries in dmesg. It seems on disk
accesses are dead. it still routes packets fine.
This is an old PII-300 with 2 IDS disks and a DVD R/W.

So that's using the old IDE drivers.
And the network and USB are sharing IRQ#11 with each other.
If you are going to be using newer kernels like this (2.6.23+),
then you might consider shifting those drives over to libata drivers.
This involves a little bit of work -- building a kernel with libata
and "ata_piix" built-in instead of the old IDE drivers,
and then rearranging /etc/fstab to match the new device names
(eg. /dev/sda instead of /dev/hda).
But at this point libata is working much better than the old IDE stuff,
and it really is worth moving things over if you can.
Cheers
