[Prism54-devel] SMC2835 report

Thu Mar 24 09:10:32 UTC 2005

Hi,

I just convinced our proxy guy to allow svn methods, so I could try the
current svn verion (529) with a 2.6.11 kernel

Compilation was clean, apart from the "usual" compile patch.

The 2835 worked well, but when ejecting it, it gave an error with a
kernel panic some seconds later. Here is what I could save from the
logs. The panic some seconds later did not make to the disk,
unfortunately.

So, procedure to reproduce:

- Insert card, configure it, use it.
- ifconfig eth1 down
- eject it from the PCMCIA slot
- see something like below.

Bye,

Joerg
