Confirm that similar regular freezing occurs only on my machine, with ext4 FS converted from ext3. Typically the freeze occurs under high disk activity; I believe when the freeze has happened, I have had a rsync job traversing whole /home, which contains a large number of small files.
I managed to get a SysRq+L stack trace, when the freeze occurred. (Photo attached; the machine was unresponsive, so can't attach it as text.) The trace is quite similar to that reported in https://bugs.launchpad.net/ubuntu/+source/linux/+bug/340628 It might be of note that the system did not initially respond to SysRq commands at first, but responded only after a few minutes. These freezes occur very frequently, typically within a few hours of uptime. This bug severely affects viability of using ext4 partitions (if the problem really has to do with ext4). Probably unrelated information: freezes occur both with the non-free Nvidia driver and the free Xorg nv driver. ** Attachment added: "Photo of a stack trace from SysRq+L" http://launchpadlibrarian.net/24078926/2009-03-19_00-25-25_1%20-%20initial%20sysrq%2Bl.png -- 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 [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
