Hi, I use btrfs on my laptop, 2.6.37-rc2 from kernel.org, under dm-crypt, as /. I use space_cache and compression (not forced). Today, my computer froze. At reboot, the kernel could not mount. The dmesg output, which I haven''t saved was speaking of a null dereference. After that I rebooted on 2.6.34, which was not very happy: mount errors (space cache ?). Now I am on 2.6.37-rc2 again, which seems to work. So I guess it might come from space_cache. I would note on a paper if this comes back. However if anybody has any clue on what specific part of the dmesg should be reported, it would be very helpfull !

If you pull down the latest I think we''ve got it nailed. -chris -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
