kernel BUG at mm/slab.c:594!
invalid opcode: 0000 [#1]



Expected results:
no crash - and perhaps something good happening automatically

Additional info:
Probably the same as http://lkml.org/lkml/2006/12/11/183 - but I can't find out
if the problem was solved...
Same BUG report, but seems to be something else:

I've just posted my dmesg as an attachment.  Note I'm running 2.6.18-1.fc6,
which I believe is currently the latest.  I only decided to start playing with
this phone today, though, so I'm not sure how long ago the bug was introduced
into the kernel.  No "external" kernel modules are being loaded here.

Not sure if this makes any difference, but this is on a Thinkpad T40 which has
intel EHCI USB2 controllers.

I was playing with the same phone on a RHEL system earlier today, and what is
supposed to happen is:

 - the system sees a USB hub and the Nokia phone on that hub
 - a device /dev/ttyACM0 is created, through which you can do everything you
would want to do

Comment 4 Paul Witt 2007-01-14 03:10:39 UTC

I forgot to mention: it's a dku-2 cable and the software on the phone is series 60

Comment 5 Bryn M. Reeves 2007-04-17 10:47:10 UTC

This sounds like bug 228231 that was fixed in 2.6.19-1.2911.6.3. Can you re-test
with a later FC6 kernel and update this bugzilla if you are still having problems?

Thanks,

Comment 6 Mads Kiilerich 2007-04-17 21:28:28 UTC

I can confirm that I don't get crash with 2.6.20-1.2944.fc6.

(I haven't been able to get any connection to the phone yet, but that is
probably the operators fault.)

I consider the issue solved. Thanks.
