I am focusing in on SMM emulation. http://www.ussg.indiana.edu/hypermail/linux/kernel/0407.3/0688.html suggests something to me. What if I am executing this on a processor other than the boot processor, and the SMM code doesn't expect this? I'm not sure where I would try this patch in freebsd, but it seems promising. Ie I read 0xe090. This trips SMM for legacy(?). SMM is entered, does something, corrupts, leaves, and then a few instructions later I crash. The suggested workaround for this (different machine and OS) is to disable the legacy mode. FreeBSD seems to do this already I think, calling: pci_write_config(self, PCI_LEGSUP, PCI_LEGSUP_USBPIRQDEN, 2); in uhci_pci_attach() _______________________________________________ freebsd-hardware@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hardware To unsubscribe, send any mail to "[EMAIL PROTECTED]"
