Package: linux-image-2.6.21-2-686
Version: 2.6.21-6
Severity: normal
When running user mode linux (particularly more than one instance) uml reports
tasks failing with random segfaults. Apparently this is a symptom of a known
kernel bug: fault information pollution.
There is a patch for the kernel problem:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff_plain;h=d18951834216eae82e2f9112416111b4f55f1849
Any chance of getting this patch applied to the kernel in lenny?

no 2.6.21 is not supported, beside beeing the infamous "quality"
release. fetch 2.6.22 from unstable or if you want newer
2.6.23-rc2 from trunk builds -> http://wiki.debian.org/DebianKernel
