Shyam, this bug was reported a while ago and there hasn't been any
activity in it recently. We were wondering if this is still an issue in
Precise+? If so, could you please run the following command from a
Terminal (Applications->Accessories->Terminal), as it will automatically
gather and attach updated debug information to this report:
apport-collect -p linux <replace-with-bug-number>
** Tags added: bios-outdated-1.12.0

Title:
GPF in ksmd cmp_and_merge_page flow
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
We hit upon this GPF in oneiric 3.0.0-14-server kernel. Just before
the upgrade to oneiric we were running natty (2.6.38-8-server) & we
never hit this one.
