Bug#436227: linux-image-2.6.21-2-686: uml experiences random segmentation faults due to fault information pollution
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?
