As was pointed out the other day, nVidia use the %gs register without saving and restoring it, in order to maintain their internal thread state. Now that FreeBSD also uses this register, that causes crashes. I believe the fix is as simple as saving and restoring %gs in the nVidia driver, and/or not letting the nVidia use %gs at all (segment registers generally belong to the OS, in any case, and stealing a CPU register of any kind for exclusive use of a driver is a pig trick). -- Terry _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "[EMAIL PROTECTED]"
