Hi, I have the same problem with amd 9950 4core cpu when copying large amounts of data from/to the lvm (4x sata HDs).
Using debian 5.0 amd64 with no packages beside official ones. One workaround for the panic is to edit /etc/xen/xend-config.sxp and change (dom0-cpus 1) And also edit every dom-u to use only one cpu Of course this is a workaround for the machine keep working... but it is not nice to run with only one cpu. After installing the packages from http://yoush.homelinux.org:8079/nikita/xenfix/ I could put back all processors and it worked well again. Just sent this e-mail as an extra confirmation that the patch works as expected. Regards, Pedro -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
