hi, just sitting in front of my linux box and seeing this coming up on
console. The whole computer stuck for ~5 sec.
it starts with:

ven# Oct  3 14:33:09 ven kernel: scsi0: Target 11 underflow - Wanted at
least 124928, got 121856, residual SG count 59.

Target 11 is a Seagate Barracuda, ST32550W

can you help me ?
