The first run (794c10fa0fa4d) = was the result of the bisection limited to drivers and fs directories. A second= run where I also added the block directory lead to a commit related to watc= hdog, which is impossible since I don't use watchdog on my computer. A 3rd run on the whole kernel tree leads to this commit: =46rom 4523e1458566a0e8ecfaff90f380dd23acc44d27 Mon Sep 17 00:00:00 200= 1 =46rom: Dave Hansen Date: Wed, 30 May 2012 07:51:07 -0700 Subject: [PATCH] mm: fix vma_resv_map() NULL pointer hugetlb_reserve_pages() can be used for either normal file-backed hugetlbfs mappings, or MAP_HUGETLB. In the MAP_HUGETLB, semi-anonymous mode, there is not a VMA around. The new call to resv_map_put() assume= d that there was, and resulted in a NULL pointer dereference: This is also strange because I don't use hugetlb. I can revert this com= mit but it doesn't change anything. Does anybody have an idea on what I could d= o to further investigate this problem. --=20 Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=3Demai= l ------- You are receiving this mail because: ------- You are the assignee for the bug.-- To unsubscribe from this list: send the line "unsubscribe linux-scsi" i= n the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
