https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=213903 --- Comment #50 from commit-h...@freebsd.org --- A commit references this bug: Author: mjg Date: Tue Jul 11 03:45:48 UTC 2017 New revision: 320885 URL: https://svnweb.freebsd.org/changeset/base/320885 Log: Remove waiters check from the inline rw wunlock routine. This is a direct commit to stable/10. r310979 is a merge of depessimisation of locking primitives. The important part was getting rid of an attempt to grab the lock in the slow path immediately after the fast path failed. In addition to that temporary checks were added before all atomic ops. They have no impact on semantic nor correctness, they only avoid an atomic operation which is likely to fail. After the addition of atomic_fcmpset and further changes said checks became pessimal and got removed. This may get merged to stable/10. Reports started showing up about a crash in all branches having extra checks. The codepath is: .. -> vm_map_delete -> __rw_wunlock_hard -> turnstile_broadcast The kernel crashed trying to wake up nonexistent waiters. The lock value as found in the vmcore matches the panicking thread, so in particular there was no waiters bit set. The bit can only be cleared by the current owner. A debug patch was provided, which reportedly had a side effect of getting rid of the issue. Also one of the reporters said that reverting the patch which adds the extra checks makes the crash go away. It was also reported that head with the fcmpset changes (explicit checks removed) also stops crashing. Finally, one user tested crashing stable/10 variant with just the rw wunlock check removed. The common case in all but one reports was an Intel Atom cpu. Claiming a cpu bug at this point is bold and I'm going to refrain from it, but right now apart from cpu-specific optimisation made by the compiler on custom kernel compiles I don't see how this can be a software bug. This will have to be investigated more. Meanwhile, restore rw wunlock to pre-r310979 state.

That said, I expect the problem to be gone on head starting with r313270 and on stable/11 starting with r315377, which also means it is included in all 11.1 builds. That said, if someone running into the crash on one of the above could confirm the newest version of their relevant branch makes the problem go away, that would be nice. -- You are receiving this mail because: You are on the CC list for the bug. ___ freebsd-stable@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=213903 --- Comment #35 from Mateusz Guzik --- Hi there, sorry for late reply. This somehow fell through the cracks. First of all there is no kernel bug per se that I can see, rather a bug in the atom cpu which started manifesting itself. There were several changes to the affected code path on stable/11 and in particular the condition which triggered the bug is gone. I don't have any reports, but I suspect stable/11 is now cleared. stable/10 will require a hack, but I'll need someone to test it as don't have the hardware to reproduce. -- You are receiving this mail because: You are on the CC list for the bug. ___ freebsd-stable@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
