Another update: this system hang issue does not appear to be related to loopback mounted image but to the xen kernel itself. After a fresh reboot with the Xen kernel (previous dmesg attached) without any DomU started or any other activities on the system a simple dd to a file will freeze the system, in this case after a few seconds, after a segfault in dd:
$ cd /tmp/ $ dd if=/dev/zero of=.tmp_file_34639236 bs=64k & [1] 4444 $ rm -f .tmp_file_34639236 $ while true > do > date; sleep 15 > done Sun Nov 11 18:14:12 CET 2007 [1]+ Segmentation fault dd if=/dev/zero of=.tmp_file_34639236 bs=64k Sun Nov 11 18:14:27 CET 2007 Very unlikely this is a filesystem issue. Booting the Non-Xen kernel the same exercise slows down the system but works very fine. dmesg booting the non-Xen kernel attached for comparison ** Attachment added: "dmesg-no-Xen.out.gz" http://launchpadlibrarian.net/10333815/dmesg-no-Xen.out.gz -- Hanging xen-create-image likely related to loopback mount https://bugs.launchpad.net/bugs/161878 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
