[wifi] kernel oops when starting wpa_supplicant

[tilman2]

I'm running shr-unstable from April 9th:
​http://build.shr-project.org/shr-unstable/images/om-gta02/openmoko-shr-lite-image-glibc-ipk--20090409-om-gta02.rootfs.jffs2
​http://build.shr-project.org/shr-unstable/images/om-gta02/uImage-2.6.28-oe1+gitr119783+901d73fe51f33032b34b2ae5612eb863ec90532a-r3.1-om-gta02.bin

The kernel version reported is 2.6.29-rc3.

When starting wpa_supplicant, the kernel oopses. I'll attach the output of dmesg and my wpa_supplicant.conf.

The following patch seems to resolve this; I really can't say if this is the correct resolution, but it seems to work for me:

Mwester, it seems like a good solution (until someone tell us otherwise). Can I create a patch with your fix and add a Signed-off-by for you with your email address?

Replying to arhuaco:

Certainly; we can back it out if there is a "more correct" way to solve this.

Commited. Closing bug.
