An update. This happens only with clang compiled kernel, gcc compiled kernel is OK. Also, this happens only in the depth of fwohci driver (where it calls DELAY). If firewire is not loaded, then there is no problem. I suspect that perhaps there is some miscompilation that results in some incorrect I/O access that later leads to NMI. Too many unknowns and guesses here, obviously. -- Andriy Gapon _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "freebsd-hackers-unsubscr...@freebsd.org"
