Subject: find_busiest_group divide error
[1.] One line summary of the problem:
find_busiest_group divide error
[2.] Full description of the problem/report:
Around June 7th I found I could no longer boot a mainline kernel. I
posted about it here on June 9th:
http://lists.kernelnewbies.org/pipermail/kernelnewbies/2014-June/010914.html
I bisected two complete times but never got to a commit that made any
sense:
https://bugzilla.kernel.org/show_bug.cgi?id=77711
I see a lot of kernel/sched/fair.c patching appeared in mainline on June
5th:
https://github.com/torvalds/linux/commits/master/kernel/sched/fair.c
So I tried checking out specific revisions and found
09dc4ab03936df5c5aa711d27c81283c6d09f495 is the latest good revision I
can boot. The first bad revision I hit is
51f2176d74ace4c3f58579a605ef5a9720befb00.
I have no idea how to fix it. I'm just a web developer/kernel tester :(
The issue affects both of my identical 32-bit file servers while all my
64-bit systems have no issues.
I'd be happy to test any patches anyone has to offer.
[3.] Keywords (i.e., modules, networking, kernel):
scheduler, find_busiest_group
[4.] Kernel information
[4.1.] Kernel version (from /proc/version):
Linux version 3.15.0-rc2-4+ (root@...s) (gcc version 4.7.2 (Debian
4.7.2-5) ) #1 SMP Thu Jul 10 17:24:56 CDT 2014
[4.2.] Kernel .config file:
Attached.
[5.] Most recent kernel version which did not have the bug:
09dc4ab03936df5c5aa711d27c81283c6d09f495
