This is unusual; I'm having trouble very close to this area. There is a remote chance it could be the same problem. Could you log this to serial and get the rest of the oops/BUG? If it's where I think it is, I've been looking at end_page_writeback() and so might have an idea or two.I tried 2.5.70-mm1 on the dual celeron at home. This one has scsi instead of ide, so I guess it is a RAID-1 problem. This machine has root on raid-1 too. I believe there where several oopses in a row, I captured all of the last one thanks to a framebuffer with a small font. Here it is: Unable to handle kernel paging request at virtual address 8a8a8ab6 *pde=0 OOPS 0000 [#1] EIP at put_all_bios+0x47/0x80 (edx was the register containing 8a8a8a8a) Process swapper pid=0 threadinfo c1352000 task=c13f52d0 Call trace: raid_end_bio_io raid1_end_request
That's POISON_BEFORE: "use of uninitialised memory", not "use of freed memory". I fiddled with the slab poisoning values, and shall undo that. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
