Re: [BUG] crash - module l440gx buggy ? interfere

[devzero]

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 ?

Re: [BUG] crash - module l440gx buggy ? interfere

[Roland]

it`s the 3rd time now that i stumbled over this, and i`m 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!

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

regards
roland
