[Xen-devel] [Xen-deve] xen/stable-2.6.32.x bare-metal: panic early exception 0e rip 10:0 error 10 cr2 0
Source: git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git Tested branches: xen/stable-2.6.32.x xen/next-2.6.32.x When trying to boot the current kernel bare-metal it will not load properly, instead i am prompted with: panic early exception 0e rip 10:0 error 10 cr2 0 at the bottom line of the screen. Here is a screenshot: http://imageshack.us/photo/my-images/10/crashtm.png/ System is: Dell PE2950 (Xeon L5335, Intel 5000 chipset) Debian 6.0.2 squeeze(stable) grub 1.98+20100804-14 Kernel .config: http://pastebin.com/bQAyC30i It has been derived from the example configurations on "http://wiki.xensource.com/xenwiki/XenParavirtOps". The kernel boots loads fine as dom0 under Xen 4.1.1 Though i know this kernel tree is intended to be a dom0 kernel, it should still be bootable bare-metal or am i mistaken? It worked previously, allthough i am unable to tell what the latest working version was. with best regards -- Andreas Olsowski _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Not only occurs on bare metal but also on HVM and QEMU. I faced some mmap() issues (see previous discuss in this list), and try to use xen.git''s kernel instead of generic one. Right now, the xen.git''s cannot boot even on bare metal! I have to find out the other way to put our servers into XEN. /Eric _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

What was the last kernel version which worked? J _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Not sure what is happening - however the 3.0.x kernel boots for you as Dom0 and baremetal, right?> > It worked previously, allthough i am unable to tell what the latest > working version was.OK. I don''t think we are going to look at this in much detail unless you have some bisection numbers. The upstream 3.x kernels are our main focus - to make sure they work properly and we haven''t really focused much on the 2.6.32. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

I have been trying to narrow it down a bit, and it seems to me that the bug was introduced somewhere between xen-2.6.32.39 and xen-2.6.32.42.

I will try to find the time to narrow it down to one exact version this weekend. -- Andreas Olsowski Leuphana Universität Lüneburg Rechen- und Medienzentrum Scharnhorststraße 1, C7.015 21335 Lüneburg Tel: ++49 4131 677 1309 _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Yes, it won''t work under that - at least not in that state. Jeremy, can you revert that patch please - it was fixing one instance of machines - and it looks to be breaking many more.
