>Description:
When compiling programs (e.g. wget, or samba-2.0.7), 4.1-stable crashes on my machine (Pentium 120, 96 megs RAM). The weird thing is, that the kernel compiled fine. Every other compilation crashed the machine hard. (Page fault in kernel mode) 
Hardware:
ATI xpert@work Mach64 gfx-card
VIA 82C586 IDE-Controller (according to dmesg)
VIA VT6102 Rhine II nic
Elsa Quickstep 1000pro PCI ISDN-card
The hardware is fairly old, however, it used to run rock solid under Linux. It's somewhat weird, that although the harddrive (a Fujitsu 8 GB IDE-drive) and the mainboard both support UDMA33, but when fbsd tries to mount the hd, it complains about a command timeout:
ad0: READ command timeout - resetting
ata0: resetting devices .. done
It does that 3 times, and then it falls back into PIO mode.
>How-To-Repeat:
compile some stuff from the ports, or transfer about 400-500 megs via NFS to the pc.
>Fix:
none
