I've tested the latest mainline kernel (v3.6-rc7-quantal, as requested) and it's working fine.
The latest precise kernel (released after my last update) still doesn't work: linux-image-3.2.0-31-generic 3.2.0-31.50 But this one does: linux-image-3.6.0-030600rc7-generic 3.6.0-030600rc7.201209232235 linux-image-extra-3.6.0-030600rc7-generic 3.6.0-030600rc7.201209232235 I hope this helps. ** Tags removed: needs-upstream-testing ** Tags added: kernel-fixed-upstream ** Tags removed: kernel-unable-to-test-upstream -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1054605 Title: Mount very slow for 22TB ext4 filesystem on Ubuntu Server 12.04.1 running kernel 3.2.0-30-generic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1054605/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
