I've got a dual pentium 3 600MHz based Intel ISP 2150 with the latest
BIOS (version 14.3).
When trying to boot from the 5.3-beta7 install CD, I get a
panic just after the copyrights. The following is printed:

kernel trap 12 with interrupts disabled

Fatal trap 12: page fault while in kernel mode
cpuid = 0; apic id = 00
fault virtual address	= 0x10
fault code		= supervisor write, page not present
instruction pointer	= 0x8:0xc062ab55
stack pointer		= 0x10:0xc1021ca0
frame pointer		= 0x10:0xc1021cb0
code segment		= base 0x0, limit 0xfffff, type 0x1b
			= dpl 0, pres 1, def32 1, gran 1
processor eflags	= resume, IOPL = 0
current process		= 0 ()
trap number		= 12
panic: page fault	=
cpuid = 0		=
uptime: 1s

This happens with or without ACPI.

When I escape to the loader prompt and boot -v -p,
I get a string of some 20 'k'-s and then the system just reboots.
I have also seen an interrupt with interrupts disabled though.

The system is 440GX based.

Any help would be appreciated.
