http://bugzilla.novell.com/show_bug.cgi?id=553690 http://bugzilla.novell.com/show_bug.cgi?id=553690#c31 --- Comment #31 from Jan Beulich <jbeulich@novell.com> 2009-11-19 15:33:19 UTC --- This log together with one of the earlier provided ones makes it clear that swiotlb code is being instructed to write over a page table, due to running off the end of a valid buffer. It is not clear however whether the buffer was originally specified improperly, or whether stored data got corrupted e.g. during I/O. Since I can't reproduce the issue myself, I'm hoping that you would be able to rebuild your kernel with the debugging patch just attached, and then try and see whether it captures the problem any earlier (and of course doesn't have any adverse side effects). Do you, btw, also run into this issue when using mem=4G on the Xen command line? Also I assume you're not having the machine do any other things while starting the guest? And from the last log I'm having the impression that only the third guest that got started actually crashed the machine - were the first two of different type, or does the problem not always occur? It would also be nice if you attached "lspci -nn" output for the machine, unless you know the problem is present on two sufficiently different ones. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
