Computer reboots after printing CUPS test page.

[Alex Pivovarov]

After printing CUPS test page from "lynx localhost:631" I get an error
described below and my computer halts. I get this error quite regulary
after printing smth through CUPS (not always but aprox. 50/50).

----------------------------------------------------------
Fatal trap 12: page fault while in kernel mode

My configuration:

soft:
FreeBSD 5.4-RELEASE #2
Kernel: GENERIC
cups-1.1.23.0
cups-base-1.1.23.0_4
cups-lpr-1.1.23.0
cups-pstoraster-8.15
ghostscript-gnu-7.07_13
ghostview-1.5
gsfonts-8.11_2

hardware:
CPU: AMD Athlon(tm) XP 1800+ (1531.03-MHz 686-class CPU) (not overclocked)
Chipset: nVidia nForce 2
RAM: 512MB DDR400 (checked by memtest86 v.3.2 - no errors)
Printer: HP LaserJet 1010 USB

I also try it on Intel Celeron 2600MHz + SIS 645 and get the same error.

May be it will be helpful - I get very similar error on NETBSD 2.0.2

P.S. Under Debian 3.1, Suse 9.3, Windows 2003 - the printer works fine
for a long time and under a heavy load on this computer.
