BUG: unable to handle kernel paging request at 00021c6e
I was unable to reproduce this on qemu at least (my test machines are
all occupied). Test case was to force use of highmem (vmalloc=) and
mount tmpfs with a swapfile in place. A heavy mix off dd writing to
on-disk and tmpfs-files over the course of 15 minutes triggered nothing
out of the ordinary. So, whatever is going on here, it's not immediately
obvious and so I'm afraid I have to make wild stabs in the dark.
Relevant people cc'd.
This bug (activating show_mem) can be reproduced without the dd on
tmpfs. From a initial ramdisk containing only a shell, some libraries
and the following init script:
: #!/bin/sh
: echo Loading....
: sleep 60
Pressing shift+scroll lock during the sleep generates an oops at the
beginning of the show_mem function also. The issue does thereby not seem
to be related to any of the kernel code compiled as modules. It pretty
much rules out tmpfs itself.
Theory 1
--------
Can we eliminate bad hardware as an option? What modules are loaded in this
machine (lsmod and lspci -v)? Can memtest be run on this machine for a number
of hours to eliminate bad memory as a possibility? I recognise that 2.6.12.6
was fine on this machine but it's possible that 2.6.34.1 is stressing the
machine more for some reason.
The kernel has been run on multiple hardware (similar (not fully
identical) type though) and memtest86+ has been run for several hours
without any trouble.

Theory 2
--------
To catch early mistakes in the memory model, can the machine be booted with
mminit_loglevel=4 and CONFIG_DEBUG_VM set in .config? I am not optimistic
this is where the problem is though. If we were making mistakes in early
setup, I'd expect a large volume of bug reports on it.

Theory 3
--------
I see this message early in boot
Phoenix BIOS detected: BIOS may corrupt low RAM, working around it.
Is there any possibility that the wrong range of memory is being reserved
and in fact the BIOS is screwing with the region of memory memmap is stored in?
Can't be fully ruled out indeed, since during memtest86+ no kernel with
ACPI loaded has been loaded the BIOS may very well be less active or be
inactive. And thus not showing any memory changes caused by BIOS RAM usage.
Theory 4
--------
with the early boot changes, is there any possibility that bootmem used the
low 64K? To test the theory, can the kernel be rebuilt with CONFIG_NO_BOOTMEM
*not* set to use the older bootmem logic?

Is there any possibility when this fails that the device is writing to
some location in memory thinking the OS has taken proper control of it
and reserved those physicaly address? (reaching I know, but have to
eliminate it as a possibility)
Tried aerdriver.forceload=y without success. Suggestions welcome on how
to rule this out.
Sorry to spread the possibilities all over the place but without a local
reproduction case, there isn't much to go on yet.
If it helps I can sent or attach the vmlinuz or even complete kernel
build dir
