5-CURRENT on IBM ThinkPad A30p

[Stanislav Grozev]

Hello,

I am trying to install FreeBSD 5.2-CURRENT (snapshot 20040202 from snapshots.jp.freebsd.org).
I was able to install it choosing Safe Mode from the boot menu, but after that whenever I try
to boot it (with, without acpi, safe mode) it panics with the following (copied by hand):

Memory modified after free 0xc45a7e00(508) val 1000100 @ 0xc45a7e00

Fatal trap 12: page fault while in kernel mode
cpuid = 0; apic id = 00
fault virtual address	= 0x1000120
fault code		= supervisor read, page not present
instruction pointer	= 08:0xc071c0aa
stack pointer		= 0x10:0xd8633984
frame pointer		= 0x10:0xd86339a0
code segment		= base 0x0, limit 0xfffff, type 0x1b
			= DPL 0, pres 1, def32 1, gran 1
processor eflags	= interrupt enabled, resume, IOPL = 0
current process		= 54 (init)
kernel: type 12 trap, code=0
Stopped at	mtrash_ctor+0x3a:	movi	0x20(%eax),%eax

I have browsed the archives and found the bit about setting ht.pci.allow_unsupported_io_range="1".
I have set it via the loader, but the same panic happens.

Any ideas would be greatly appreciated
