I hope someone can help me. I have a server with two SSDs that contain a mirrored btrfs volume holding /, and multiple HDDs that are in a btrfs RAID10 array. I updated to linux 3.7.3 in testing, and it failed to boot. I booted from a USB drive, and reinstalled 3.6.?, and I still get failed to set xfermode (err_mask=0x40). I don't see anything in dmesg that makes a difference. The only thing that changed was the kernels, back and forth. Does anyone have an idea, or am I going to have to re-install? Thanks.

Hi Jameson, a blind shot here since I'm not familiar yet with SSD setups: did you tried running a fsck? In the past I had a similar situation with conventional hard disks and the problem was some corrupted data in /boot.

Hope you have your beast up soon!

Yes. I had actually forgotten that I had a separate ext4 boot partition. I've ran fsck on it as well as btrfsck on my mirrored root, and my raid10 array. All return fine. During boot, between some of the xfermode errors, I can see the message where it is looking for btrfs file systems, and then a repair console which says that the root filesystem can't be found which doesn't respond for some reason. I'll try to find another keyboard to see if it will make a difference. I did another install of of the old 3.6 kernel, and noticed that it threw an error about not being able to find the root filesystem at that point also. Any further diagnostic advice will be appreciated.

Also, it turns out changing USB keyboards makes no difference. I don't think I have a PS/2 keyboard, anymore. I've currently copied all of my data from my SSD array to a HDD, and plan on trying to get it to boot. I've successfully ran mkinitcpio and grub-mkconfig from a chroot on the HDD which did not return the error about not finding the root filesystem, so I'm hopeful it will at least get me back up and running. I forgot to grub-install, though, so I'll have to wait until I get home to test it.

In case anyone else runs into this, I needed to patch the kernel with the patch provided in this bug: https://bugzilla.kernel.org/show_bug.cgi?id=51881
