same/similar behaviour with

l440gx and container
l440gx and acpiphp

after load of l440gx, container and acpiphp modules do also hang my system on load/unload.

maybe l440gx leaving the system in some weird state after probe ?

Betreff: [BUG] crash - modules l440gx and parport_pc interfere

there seems some weird interference between l440gx and parport_pc modules

i can reproduceable crash my box by either:

modprobe parport_pc;modprobe l440gx;rmmod parport_pc

or

modprobe l440gx; modprobe parport_pc;rmmod parport_pc

this happens on 2.6.24rc6 and also older kernel (2.6.22)

nothing in dmesg - just

Quoted 2 lines

JEDEC: Found no L440GX BIOS device at location zero JEDEC probe on BIOS chip failed. Using ROM

Quoted 6 lines

because i haven`t appropriate hardware.

don`t know if this is a bug in parport_pc or l440gx but maybe its worth reporting.

roland

its the 3rd time now that i stumbled over this, and im 100% sure now that there is an issue l440gx module/driver.

cause it`s constantly bugging me when module testing and always need to remember to exclude that module, i created bugzilla #10664 for this:
http://bugzilla.kernel.org/show_bug.cgi?id=10664

as you can see that there are bugs in the kernel (important or not) for which nobody really cares ;) ok, not a big deal here, but it`s a bug!

id like to encourage everyone to file a bugzilla - this helps avoiding loss of non-serious bugs in lkml deepness (im sure there are a LOT!)
