No, thanks for spotting it, but please remove from the regressions report: it's not a regression in 3.3-rc but in linux-next - don't take my word for it, check the commit and you'll not find it in 3.3-rc.

Please send it again if not. FWIW, we've been getting a bunch of these since 3.0 in Fedora. I've been trying to come up with some way of trying to reproduce them myself, without any luck. Some of our users seem to hit them surprisingly easily. At first I started wondering if it was just bad hardware, but the frequency that we've been getting reports seems to suggest something more screwed up. https://bugzilla.redhat.com/buglist.cgi?bug_status=NEW&bug_status=ASSIGNED&bug_status=MODIFIED&bug_status=ON_DEV&bug_status=ON_QA&bug_status=VERIFIED&bug_status=RELEASE_PENDING&bug_status=POST&classification=Fedora&component=kernel&product=Fedora&query_format=advanced&short_desc=bug+page+map&short_desc_type=allwordssubstr&version=15&version=16&version=rawhide&order=bug_id&query_based_on= Until last week, we only had reports up until 3.2, but now that the F17 alpha is getting tested, people are starting to hit it on 3.3rc too I'll try a test build with that commit backed out for our users to try out next week.

Please send it again if not. FWIW, we've been getting a bunch of these since 3.0 in Fedora. I've been trying to come up with some way of trying to reproduce them myself, without any luck. Some of our users seem to hit them surprisingly easily. At first I started wondering if it was just bad hardware, but the frequency that we've been getting reports seems to suggest something more screwed up. https://bugzilla.redhat.com/buglist.cgi?bug_status=NEW&bug_status=ASSIGNED&bug_status=MODIFIED&bug_status=ON_DEV&bug_status=ON_QA&bug_status=VERIFIED&bug_status=RELEASE_PENDING&bug_status=POST&classification=Fedora&component=kernel&product=Fedora&query_format=advanced&short_desc=bug+page+map&short_desc_type=allwordssubstr&version=15&version=16&version=rawhide&order=bug_id&query_based_on= Until last week, we only had reports up until 3.2, but now that the F17 alpha is getting tested, people are starting to hit it on 3.3rc too I'll try a test build with that commit backed out for our users to try out next week.
