Hi,
I'm trying to boot 2.6.16-rc1 on a T42 Thinkpad notebook.
No serial port for serial console. I don't think that networking
is alive yet (for network console ?).
Anyone recognize this? got patch?
This is just typed in, so could contain a few errors.
Unable to handle kernel NULL pointer dereference at virtual address 00000001
printing eip:
00000001
*pde = 00000000
Oops: 0000 [#1]
SMP DEBUG_PAGEALLOC
Modules linked in:
CPU: 0
EIP: 0060:[<00000001>] Not tainted VLI
EFLAGS: 00010202 (2.6.16-rc1)
EIP is at 0x1
<skip reg. dump>
<skip stack dump>
Call trace:
show_stack_log_lvl+0xa5/0xad
show_registers+0xf9/0x162
die+0xfe/0x179
do_page_fault+0x399/0x4d8

Code: Bad EIP value.
Thanks,

Both 2.6.15 and 2.6.15.1 boot OK for me.
.config for 2.6.16-rc1 is at

If you disable CONFIG_PNP and CONFIG_ISAPNP options does that help?

Nope, no change. Any other suggestions?
I just booted with a KOBJECT_DEBUG
built kernel and it's failing after:
kobject platform: registering, parent: <NULL>, set: devices

Can you enable CONFIG_DEBUG_DRIVER and see if that helps?

Yes. Transcribing that:
kobject platform: registering, parent: <NULL>, set: devices
DEV: registering device: ID = 'platform'
kobject_uevent
PM: Adding info for No Bus:platform

furthermore, this happens on 2.6.16-rc1 and 2.6.16-rc1-git4,
but <platform_notify> is not at the same memory address in
my builds, so it smells more like a bad ptr reference
somewhere than like bad memory IMO.

Hm, can you do a git bisect from 2.6.15 to 2.6.16-rc1 to see if you can
find this?

follow-up: for now I guess I'll blame the oopsen that I was seeing
on a bad compiler or just karma. I don't have proof except that
I installed a new distro + gcc and no longer can cause/create the
problems. (was using gcc 3.4.3 from Mandriva 2005)
thanks,
