Summary:
ps/killall hangs =>
ada tests during gcc build trigger kernel problem I will do more tests tonight (like building gcc on kernel-linus without other load on the machine). Also important note, this is building on a tmpfs. I could reproduce when building gcc on 3.18.3-server-1.mga5 without anything else running on the machine. I could not reproduce with -linus-3.18.3-1.mga5 (tried 3 times). I could also not reproduce with 3.18.2-server-1.mga5 (tried only once) Assignee:
bugsquad =>
tmb Reproduced on 3.18.3-desktop-1.mga5 too Hm, iirc there was a thread recently on LKML regarding mm/thp relating to expand_downwards... But it's weird the 3.18.2 worked but 3.18.3 not as I didn't change anything besides the upstream -stable patch (and dropped merged ones) and since kernel-linus works (and is built with the same defconfig as desktop kernel) I guess some of our other patches got in trouble with 3.18.3... Hm, If you have time, can you try to disable the AUFS patches: fs-aufs-3.18.patch fs-aufs-3.18-modular.patch fs-aufs-adapt-for-3.18.1-d_child-change.patch and see if the problem goes away ? For the record, it also happens when building on ext4 instead of tmpfs. I built a kernel without aufs (there is also a line to remove in the spec) but could still reproduce. Given the problem I will try without the x86-mm* patches I couldn't reproduce after dropping the 3 patches:
x86-mm-consolidate-VM_FAULT_RETRY-handling.patch
x86-mm-move-mmap_sem-unlock-from-mm_fault_error-to-c.patch
x86-mm-fix-VM_FAULT_RETRY-handling.patch
The second one looks suspicious (double up_read):
up_read(&mm->mmap_sem);
if (unlikely(fault & VM_FAULT_ERROR)) {
+ up_read(&mm->mmap_sem);
Ah this seems due to the inversion of order of patches, the first one was moving it out but is now adding it outside, this one was originally adding it inside but it was not supposed to already be outside. I committed a possibly fixed patch, time to sleep, I'll test with it tomorrow. Oops, well spotted... I wonder how I managed to get them reversed... :/ That is the correct fix. Tried with the fixed patch, and things are good. Do you have another kernel planned soon or should I upload this one? kernel-3.18.3-2.mga5 already building and should be uploaded within ~1 hour Ah sorry, should have checked :) Closing Status:
