Could this corruption be caused by a pci card/driver? I am asking as I am using a new dvb-t card (asus p7131) and the oops happened after 5 or 6 days of uptime just about a day after watching some movie (very bad reception/lots of errors). However this machine used to have uptimes of months before the dvb card was in there and the kernel version upgrade (don't know which version that was...). Anyway I am not sure if this is reproducible, but I will keep memtest running today and then proceed as you said...
