Re: [Bug 43359] LVM volumes not detected

I am using CentOS 6.x and I hit this bug with 3.5-rc2. I tried to look in to the boot process and found that the initramfs generated from 3.5.-rc2 is not good for lvm root. It was missing /lib/modules/<uname -r>/kernel/drivers/md/*". Also /sbin/ doesn't have lvm_scan and was missing a bunch of other files too. CCing initramfs folks. Any help?

https://bugzilla.kernel.org/show_bug.cgi?id=43359--- Comment #1 from François Valenduc <francois.valenduc@tvcablenet.be> 2012-06-10 06:12:06 ---This problem seems impossible to bisect. 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 watchdog, which is impossible since I don't use watchdog on my computer. A 3rd run on the whole kernel tree leads to this commit: From 4523e1458566a0e8ecfaff90f380dd23acc44d27 Mon Sep 17 00:00:00 2001 From: Dave Hansen <redacted> 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() assumed that there was, and resulted in a NULL pointer dereference: This is also strange because I don't use hugetlb. I can revert this commit but it doesn't change anything. Does anybody have an idea on what I could do to further investigate this problem. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.-- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
