Bug#588509: linux-image-2.6.32-5-amd64: hangs under Xen after Write protecting the kernel read-only data: 4220k
Package: linux-2.6
Version: 2.6.32-16
Severity: important
I have been running linux-image-2.6.32-5-amd64 2.6.32-15 mostly
without problems (except for #580889) since 2010-06-14 in debian
squeeze running under Xen.
When I heard that -16 includes CONFIG_KPROBES I wanted to test it
early. I installed the package from unstable with
wget http://ftp.fi.debian.org/debian/pool/main/l/linux-2.6/linux-image-2.6.32-5-amd64_2.6.32-16_amd64.deb

sudo xm sysrq lindi1 r
sudo xm sysrq lindi1 b
which suggests that the kernel is totally dead.
