I think I am bitten by this, too, on AMD64, with a root fs converted from ext3 to ext4 using
tune2fs -O extents,uninit_bg,dir_index /dev/DEV linux-image-2. 2.6.28-11.42 I have not found a way yet to trigger, "rm -rf" on ten thousand files once did not. On an irregular basis I can see any app doing I/O to freeze for about 3 minutes. Causing apps to do I/O (opening files etc) during that period freezes them, too. I can continue working with anything that does not require/trigger disk I/O. So this in fact seems to be a kernel lock on any disk I/O. Periods between I/O freezes vary, it may be hours and sometimes only minutes. Heavy disk I/O is not required. There is nothing suspicous in any of the log files in /var/log/ -- Soft lockups (freezes) when deleting files from ext4 partitions on 2.6.28 https://bugs.launchpad.net/bugs/330824 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
