From: Gianluigi Tiesi <sherpya@netfarm.it>

Package: linux-image-2.6.26-2-xen-amd64
Version: 2.6.26-26lenny1
Severity: critical
Justification: breaks the whole system


I've recently updated kernels from debian security repo:
linux-image-2.6.26-2-xen-amd64 2.6.26-26lenny2
supposed to address CVE-2010-3699

but instead makes dom0 and domU unusables and even freezes dom0
this happens only if using blktap2, i.e. tap:aio in xen config,
perhaps not working by default on lenny because of a missing link
(I filled a bug ages ago)

I'm attaching some kernel logs

I had to revert back to lenny1 version


Regards
