New submission from eugene <a_burza at mail.ru>:

I cannot boot with 1.7-DEVEL from Jan 20th.
The hardware is DELL Inspiron 1300, i915 chipset, celeron-m 1.6GHz

npx0:<math processor>[tentative] on motherboard
npx0:INT 16 interface
using XMM optimized bcopy/copyin/copyout
npx0:<math processor>[attached!] on motherboard
acpi0:<DELL D05> [tentative] on motherboard

Fatal trap 12: page fault while in kernel mode
fault virtual address = 0x24
fault code            = supervisor read, page not present
instruction pointer   = 0x8:0xc02d76fa
stack pointer         = 0x10:0xccbfcc78
frame pointer         = 0x10:0xccbfcc88
code segment          = base 0x0, limit 0xfffff, type 0x1b
                      = DPL0, pres 1, def32 1, gran 1
processor eflags      = interrupt enabled, resume, IOPL=0
current process       = Idle
current thread        = pri92(CRIT)

type 12 trap, code = 0
stopped at lwkt_sendmsg+0x4a xalll *0x14(%edx)

If i turn ACPI off in the boot menu, loading process hangs with no message after
probing parallel ports.

The same failure was found on an Intel 845 hardware, but on VIA KT133 with
Athlon 900 or with Duron 1300 hardware everything was OK.
