SubjectRe: 2.6.0-test6-mm4 - oops in __aio_run_iocbs()
From
Date
I'm been testing AIO on test6-mm4 using a ext3 file system and
copying a 88MB file to an already existing preallocated file of 88MB.
I been using my aiocp program to copy the file using i/o sizes of
1k to 512k and outstanding aio requests of between 1 and 64 using
O_DIRECT, O_SYNC and O_DIRECT & O_SYNC. Everything works as long
as the file is pre-allocated. When copying the file to a new file
(O_CREAT|O_DIRECT), I get the following oops:


Unable to handle kernel paging request at virtual address 6b6b6b6b
printing eip:
