Can you enable frame pointers to get an accurate stack trace? x86 can be accurate without, but I don't think this was ever implemented for UML. Because I'm not sure if below cfq_close_cooperator is being called again, or if it's just garbage (as I guess). Anyway, it's still likely that the crash is on hweight32. Also, it'd be interesting to diff your configuration with the one used by people the patch works for. Say, $ grep HWEIGHT .config (if there are any CFLAGS set in ARcH_HWEIGHT_CFLAGS, that would be a problem as far as I see). > EIP: 0073:[<081c4fcb>] CPU: 0 Not tainted ESP: 007b:08300b40 EFLAGS: 00010297 > Not tainted > EAX: 00000000 EBX: 190d2000 ECX: ffff8aea EDX: 00000000 > ESI: 191f4930 EDI: 191ef900 EBP: 191f4930 DS: 007b ES: 007b > 08300794: [<0805e65f>] segv_handler+0x3f/0x60 > 083007a4: [<081c4fcb>] cfq_close_cooperator+0x4b/0x180 > 083007b0: [<0806eec5>] sig_handler_common+0x55/0xa0 > 083007f0: [<081c4fcb>] cfq_close_cooperator+0x4b/0x180 > 08300828: [<0806f063>] sig_handler+0x23/0x40 > 08300830: [<0806f2bd>] handle_signal+0x5d/0xa0 > 08300850: [<080715f7>] hard_handler+0x17/0x20 > 0830089c: [<081c4fcb>] cfq_close_cooperator+0x4b/0x180 > 08300a4c: [<0807a3eb>] T.696+0x9b/0xc0 > 08300a74: [<08079425>] enqueue_task+0x45/0x60 > 08300a94: [<0807945f>] activate_task+0x1f/0x30 > 08300aa0: [<080794d8>] try_to_wake_up+0x68/0xa0 > 08300acc: [<0809369f>] autoremove_wake_function+0x2f/0x60 > 08300ae8: [<0807754f>] __wake_up_common+0x4f/0x80 > 08300b18: [<08077837>] __wake_up+0x47/0x60 > 08300b3c: [<081c4fc6>] cfq_close_cooperator+0x46/0x180 > 08300b58: [<081c5440>] cfq_completed_request+0x2a0/0x560 > 08300b90: [<081b7fce>] elv_completed_request+0x7e/0xf0 > 08300ba8: [<081b98f6>] __blk_put_request+0x36/0xf0 > 08300bc0: [<081b9b26>] blk_finish_request+0x176/0x1d0 > 08300be0: [<081b9ea1>] blk_end_bidi_request+0x41/0x60 > 08300bf4: [<08068e8d>] ubd_intr+0x2d/0xf0 > 08300c14: [<080a6b32>] handle_IRQ_event+0x32/0xc0 > 08300c34: [<080a6c1b>] __do_IRQ+0x5b/0xb0 > 08300c50: [<0805b364>] do_IRQ+0x24/0x40 > 08300c5c: [<0805b59b>] sigio_handler+0x5b/0x80 > 08300c70: [<0806eec5>] sig_handler_common+0x55/0xa0 > 08300c80: [<0806efb5>] real_alarm_handler+0x35/0x40 > 08300cbc: [<080739f0>] __delay+0x20/0x30 > 08300ce8: [<0806f063>] sig_handler+0x23/0x40 > 08300cf0: [<0806f2bd>] handle_signal+0x5d/0xa0 > 08300d10: [<080715f7>] hard_handler+0x17/0x20 -- Paolo Giarrusso - Ph.D. Student http://www.informatik.uni-marburg.de/~pgiarrusso/ ------------------------------------------------------------------------------ ThinkGeek and WIRED's GeekDad team up for the Ultimate GeekDad Father's Day Giveaway.
