Hi, I reported this bug on my distribution (Archlinux) but as we just call mount -a , I'm sending it upstream. (orig bug: https://bugs.archlinux.org/task/24598 ) Description: with 2.6.39 kernel I can get in conditions when mounting a btrfs partition segfaults (I already reported upstream - http://article.gmane.org/gmane.comp.file-systems.btrfs/11135 ). After this, the boot process continues, the issue is: after the crash, other partitions from fstab don't get mounted. Though there's no error on them and I can flawlessly mount them manually. What I think happens: the mount process stops (crashes?) What should happen: mounting the corrupted partition should fail (/home in my case), but other partitions should be probed normally (/var /tmp ...) Steps to reproduce: during boot, ensure mounting one partition crashes :P, then other parts are not mounted. Thanks, Mark PS sorry if double post, i got mail delivery failure. dmesg follows: [ 56.994241] loop: module loaded [ 57.172283] Btrfs loaded [ 57.191655] device label store devid 1 transid 26106 /dev/dm-3 [ 57.218783] device label home devid 1 transid 450932 /dev/dm-2 [ 57.459448] scsi 4:0:0:0: Direct-Access Generic- Multi-Card 1.00 PQ: 0 ANSI: 0 CCS [ 57.460293] sd 4:0:0:0: Attached scsi generic sg1 type 0 [ 57.467030] sd 4:0:0:0: [sdb] Attached SCSI removable disk [ 61.585618] EXT4-fs (sda4): warning: checktime reached, running e2fsck is recommended [ 61.671534] EXT4-fs (sda4): re-mounted.
