Hi, [ hijacking my own thread in order to avoid posting the dmesg twice... ]
I tried to enable AHCI mode on this computer with the intel 5400 chipset on board. This resulted in the kernel not finding the disks, after they were registered fine with the BIOS. So I thought, I'd peek at the disks using the CD, but running bsd.rd caused a hard crash which required me to press the reset button. This is the error message that I got (typed from a blurred image): ... isa0 at mainbus0 com0 at isa0 port 0x3f8/0 irq4: ns8240, .. fifo fatal integer divide fault in supervisor mode trap type 8 code 0 rip ffffffff88291c53 cs 0 rflags 286 cr2 0 cpi e rsp ffffffff f8960725e0 The operating system has halted. Please press any key to reboot. rebooting... At that point, the machine requires me to press the reset button. I don't know if this has something to do with the fact that I'm using an USB keyboard or not (legacy support is enabled). The machine runs fine when I have AHCI support switched off. Kind regards, --Toni++
