Sorry, I should have do the backtrace on the source with the date of the kernel. It was running spec_vnops.c:1.194 596: DEV_STRATEGY(bp); I don't understand what you want me to examine there as the arguments are not usefull anymore (or are they?). > >#15 0xc01edc7b in spec_specstrategy (ap=0x0) at ../../../fs/specfs/spec_vnops.c:633 > > This, I think is impossible, so I think we should assume that something > overwrite some memory and cleared out some bits which should have > survived. That was my feeling too, it wouldn't have gotten so deep with NULL arguments. Haven't checked the code so it is only an assumption. Any idea's what to do now or what to do when I am able to reproduce it?
