oops on b43 insertion on mips

oops on b43 insertion on mips

[Tomasz Chmielewski]

I just compiled 2.6.25.4 for BCM47XX (little endian MIPS).

When I try to insert a b43 module, the kernel oopses. Are there any 
fixes for that?

b43-phy0: Broadcom 4318 WLAN found
Data bus error, epc == 8013406c, ra == 801b28b4

We'll need symbol info to answer your question.

Are you running openwrt?
It currently has a linkage bug. People are working on it.
If you're not running openwrt, please provide useful debugging information.

Yes, it is build from openwrt sources.

Do you have any pointers to that linkage bug (where it was discussed etc.)?

It's discussed in a private developer channel.
The fix will be committed as soon as it is available.

PS: Next time please submit these bugreports to the openwrt bugzilla.
    That's really the only place where you can find help.
    But you don't need to post this bug to bugzilla, as its fix is
    work in progress and will be committed when it's done.
