Hi, I updated my kernel from 2.6.36 to 2.6.37 today but now I can''t boot anymore. The kernel sends BUG messages for BTRFS and couse of that different services won''t start correctly. Which services are affected seems to chance from boot to boot and at the end the computer hangs and my only change to reboot is using MagicSysRQ. I could save the output of dmesg after one boot (which was hard couse the time I can log me in and do things till the system hangs is short). Also when I''m using magicSysRQ for syncing/unmounting partitions the BUG messages are looping a few seconds. Here is the relevant part of dmesg: http://pastebin.com/ideNvhBH And (if needed) the full dmesg: http://pastebin.com/xDEct6TZ The dmesg after booting with 2.6.36: http://pastebin.com/puT6Wx0v The output of btrfsck: http://pastebin.com/9HbkVwLf And a (bad quality) image of the (end of the) message when using MagicSysRQ: http://img17.imageshack.us/img17/6895/dsc01892ja.jpg I can still boot with the old 2.6.36 kernel. Is there any way to access my data correctly with the 2.6.37 kernel? P.S. Sorry for my bad english. :)
