n/a: install hangs
>Description:
This is a first install of FreeBSD on this intel i386 (PIII 667 MHz)machine. Other OS' run well on it.
I've configured the kernel, resolved conflicts. At Storage I have only ATA disk controller (ata0 and ata01), floppy disk controller. I've eliminated all network drivers.
After saving, probing begins and ends. The installer hangs on "Mounting root from ufs:/dev/md0c"
The last lines are:
ad0: 19092MB <ST320423A> [38792/16/63] at ata0-master PIO4
acd0: CDROM <Compaq CRD-8402B> at ata1-master PIO4
Mounting root from ufs:/dev/md0c
Fatal trap 12: page fault while in kernel mode
