| |
Hi, Hope you all enjoyed your Christmas break, if anyone's still around heres one to look at :) (oops message and decode at the end).
I got the oops+panic by doing "mount /dev/hdd /cdrom -o loop" Box is highmem 64G with 192M ram and SMP kernel on UP. The oops is reproducible and produces a similar trace each time (a bit of noise from other subsystems). And yes the symbol resolving is all correct.
ll_rw_blk.c: end_that_request_first() <--snip--> if (!bio->bi_size) { req->bio = bio->bi_next; if (unlikely(bio_endio(bio, uptodate, total_nsect))) BUG(); <==== [1] total_nsect = 0; } <--snip--> [1] looks like we're hitting it there but bio_endio _never_ returns non zero, did we just drive off the edge of the world!? =)
