Hi, I''ve upgraded my system to 2.6.31-rc5 some days ago. Yesterday i''ve discovered that this kernel produces some berserk btrfs-cache processes: There are about 4 of them and they use ~95% sys-cputime. About 20 seconds after they started ''freaking out'' all writes to BTRFS will block and umounting also doesn''t work anymore. Reading the volume still works (mostly) and there appers to be no disk activity (iostat/top reports nothing unusual). This isn''t normal, isn''t it? ;-) Everything appears to work fine on Linux 2.6.31-rc3 Regards, Adrian -- 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
