Downloaded and FLASHed BIOS from A06 to Dell's latest, A09 this evening. No improvement. Also built and installed a new kernel from cvsup this afternoon. No improvement. Have a hyperthread-able P4 with hyperthreading disabled in the BIOS. Enabling HT did not prevent the panic. Copy of /var/run/dmesg.boot using "boot -v" and acpi disabled as described above is at http://home.hiwaay.net/~dkelly/dmesg.boot A curious thing is with HT disabled in BIOS FreeBSD still lists hyperthreading in the CPU capabilities. Oh, and apparently the dmesg buffer isn't big enough to hold everything "boot -v" wants to say. Surely there is a way to make it bigger? -- David Kelly N4HHE, dkelly@HiWAAY.net ======================================================================== Whom computers would destroy, they must first drive mad.
