Re: kernel BUG at fs/btrfs/inode.c:4676!
2011-06-06 12:19:56 +0200, Marek Otahal: Hello, the issue happens every time when i have to hard power-off my notebook (suspend problems). With kernel 2.6.39 the partition is unmountable, solution is to boot 2.6.38 kernel which 1/ is able to mount the partition, 2/ by doing that fixes the problem so later .39 (after clean shutdown) can mount it also. [...] I've just been hit by this (3.0). I dug up a 2.6.38 kernel and got it back running just the same. Has any progress made on this?

I would have liked to reproduce it last night and show it to you this morning, and that way I'd double-check that it really is the *same* BUG().

If you can come up with a testcase to reproduce I would love you forever ;). If I get done what I wanted to do today I will try and reproduce. Thanks, Josef ...I was getting ready for you eternal love, Josef :P...but I can't reproduce it 100%, like 70% success-rate. The test-case is quite easy, 1. mount the FS, just with compress-force=lzo option // I didn't try without, but on my other btrfs partition that doesn't use compression the err never happened ...so, can the others who experience the bug confirm compress=lzo used? 2. cd to it create a file (not sure if needed) 3. hard power-off To reproduce my tests: dd /dev/zero /btrfstest bs=1M count=256 (min required for default mksf.btrfs) losetup /dev/loop0 /btrfstest mkfs.btrfs /dev/loop0 mount -o compress-force=lzo /dev/loop0 /mnt/tmp vim /mnt/tmp/hello.txt ---power off! How long do you wait between these two steps? I've not been able to reproduce this and I've done it maybe 5 times. Either I've fixed it in my tree (yay!) or I'm doing something wrong (boo!). Thanks, Josef Not much but not immediately too, I'd say like ~5s. Did ls, df and quit. Tomorrow I'll try if I can spot a difference. Btw, is there a way to simulate power-off on a loopback-fs? Like to kill the loopback device while fs is mounted or some way? So I don't have to stress the poor hw :) Thank you, Mark -- Marek Otahal :o) signature.asc Description: This is a digitally signed message part.

kernel BUG at fs/btrfs/inode.c:4676!
Hello, the issue happens every time when i have to hard power-off my notebook (suspend problems). With kernel 2.6.39 the partition is unmountable, solution is to boot 2.6.38 kernel which 1/ is able to mount the partition, 2/ by doing that fixes the problem so later .39 (after clean shutdown) can mount it also. Attached dmesg follows.
