Unfortunately it seems this bug is still an issue. Can you confirm this issue exists with the most recent Lucid Lynx 10.04 release - http://cdimage.ubuntu.com/releases/lucid/alpha-2/.

I managed to reproduce this quite reliably so did some trials to find out how to improve things. This is 64bit dom0 on Xen 3.3.0 (On Centos) on Dell 2940s The domU is a 32bit Hardy box with 1G ram. With all the available hardy Xen kernels, this soft lockup kept happening. I tried also tried clocksource=jiffies. Then I tried the latest Intrepid kernels and the problem was solved. As I understand, the Intrepid kernel has the proper kernel.org upstream xen support (rather than the forward ported patch from 2.6.18 as is Hardy iirc). So whilst this solves the problem (for me), it's a pretty big change and isn't something I'd expect to see backported to Hardy. The new upstream Xen stuff changes the way block devices and the console are done, so you can't switch without some tweaks to your Xen configs (and guest OS config) but other than that it seemed to work fine with Hardy. Incidentally, I replaced this domU with a 64bit Hardy install, with the standard 64bit Hardy kernel, and that also solved the soft lockups. -- xen virtual Machines and Dom0 crashes with BUG: soft lockup - CPU#0,CPU#1,CPU#2,CPU#3 stuck for 11s! https://bugs.launchpad.net/bugs/259487 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

I have a Dell 6650 running whatever the latest xen server image is (and I run update/upgrade/dist-upgrade frequently). One DomU locks up pretty regularly with BUG: soft lockup - CPU#1 stuck for 11s!, usually during large file transfers. DomU Kernel version is 2.6.24-19. The bug *requires* destroying the DomU and restarting it. Its pretty clear after reading many bug reports about this that it is in the Kernel somewhere (and the kernel team has responded by changing their policy about bug reporting). It is clearly NOT hardware or application specific, as this is reported on many platforms and appears to not have a consistent trigger. Potentially, this is related to SMP, or PAE, although I find that listing these as an area of issue is an easy scapegoat, even if it may be true. Id really like someone who KNOWS what this bug is caused by to provide a definitive answer somewhere that can be seen by the public, and if possible provide a workaround or targeted date for release of fix.

Hi, I get this bug since the 2.6.24-16-xen kernel mostly in some of my running domU's. Today one domU with the 2.6.24-22-xen kernel stopped running while executing 'apt-get update'. This bug ist not CPU specific. My systems are running on ML110 XEON DualCore, ML110 P4, ML115 Opteron and DL160 QuadCore Systems. I noticed, that increasing the assigned memory size reduces the chance of running into this bug. -- xen virtual Machines and Dom0 crashes with BUG: soft lockup - CPU#0,CPU#1,CPU#2,CPU#3 stuck for 11s! https://bugs.launchpad.net/bugs/259487 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

Hi Forall, This is one annoying bug! Just wondering how you installed the package from lenny into etch? I added the repository to my etch source.list and that generated 'merge' errors. I've downloaded the deb file itself from the url you gave, but when I went to install (with dpkg -i) it produced a lot of dependency errors. Am I meant to just keep download deb files and going through dependencies until they eventually resolve, or is there a better way?
