Public bug reported:
I'm running 2.6.24-18-xen and dmesg shows this error message
BUG: unable to handle kernel paging request at virtual address
00100100
as soon some load or I/O is generated.
Even a simple kernel-upgrade (to version 2.6.24-19-xen) locks up the
dom0. Currently running domU are not affected, but most of the time a
login to the dom0 via ssh is no longer possible.
I've attached the full dmesg output and lspci information.
I found a few other similar kernel bugs with a notice to try kernel
2.6.27 of intrepid, but I couldn't find a xen-version of that (only
linux-image-2.6.27-2-generic / -server / -virtual).
