Just want to note that I am experiencing this also, to near-disastrous results.

Symptoms: log spew seen in 'dmesg' quickly filling up logs in '/var/log';
top shows a 'dd' process pegging a CPU, running as root, which I believe
is doing the writing. This has caused my system to lock up hard, and also
take a couple of tries to reboot (that's pretty bad). No problems with this
ever in the past.

How did this garbage get into the kernel in the first place?
