Hi Stefan,
When I start a Virtual Machine, during the guest's boot, IPIs are sent and received correctly between CPUs, but after a few seconds I get: spin lock 0xffffffff8164c290 (smp rendezvous) held by 0xfffff8000296c000 (tid 100009) too long panic: spin lock held too long
Is this on a lightly loaded machine ? I've not looked at your diff in detail but it's possibly a code path where a spinlock wasn't unlocked, leaving another CPU spinning.
later, Peter. _______________________________________________ freebsd-virtualization@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-virtualization To unsubscribe, send any mail to "freebsd-virtualization-unsubscr...@freebsd.org"
