Bug#428028: linux-image-2.6.18-4-686-bigmem: possible mutex deadlock; multiple pids stuck in D state near __mutex_lock_slowpath+0x4a/0x79
Package: linux-image-2.6.18-4-686-bigmem
Version: 2.6.18.dfsg.1-12etch2
Severity: normal
I've seen some issues like this in the past, were processes will start
collecting in the D state (waiting on disk or i/o etc). I almost caught
a crashdump (not sure how usefull that would have been). Fortunate for
us however, my sysrq-trigger for showTasks worked. I'm only pasting a
few pids here.

If you need something else, reply at will (to bts, I almost never check
