Same behaviour with self compiled kernel (after csup to 7, make buildworld, make buildkernel,make installkernel, reboot, so still in the 6er world). Some information I wrote down manually: Fatal trap 12: page fault while in kernel mode cpuid = 0; apic id = 00 fault virtual address = 0x4 fault code = supervisor read, page not present (-- stack- und frame pointer, code segment --) processor eflags = interrupt enabled, resume, IOPL = 0 current process = 20 (irq9: amd0) trap number = 12 Kernel with no SCSI driver (amd was the only one) boots and works well, but no SCSI of course. SCSI adapter is a TEKRAM DC-390 with Plextor PX20 CDROM, CD writer SANYO CRD-2 and Scanner UMAX ASTRA 1220S. >How-To-Repeat: >Fix: (I need some advice, how to provide more useful information) >Release-Note: >Audit-Trail: >Unformatted:
