Bug#423134: BUG: unable to handle kernel paging request at virtual address
Package: linux-patch-debian-2.6.18
Version: 2.6.18.dfsg.1-12etch1
It seems like even the newest debian kernel patches doesn't contain the
patch http://bugzilla.kernel.org/show_bug.cgi?id=7727
I used linux-patch-debian to compile my own xen domU kernel package. It
passed all my tests and used to work stable under load within about a
month but then I got in syslog:
