without any info, we cannot tell anything either.
so this is just the blame game: who comes last takes the blame.

I'd say it is hardware, if it was drbd, why would it be only you?

you could try 
  to add explicit sync groups to your config.
  to change the drbd protocol
  to run an UP kernel on your smp box,
  to tcpdump the connection "tcpdump ... -s0 -xX"
    and see if there is something suspicious.
  do some other weird things

and see if it changes anything.  if it disappears with the change, and
you can reproduce it without the change, we might get a clue.
