kernel BUG at mm/slub.c:2834!

[woutervh]

Hello all,

Currently we're having an issue on our imx53-based platform. It's running the 2.6-imx kernel. After some time of running, we are getting issues like "kernel BUG at mm/slub.c:2834!", then sshd stops while trying to login. Sometimes X crashes, or all random things seem to be having issues. Somebody can lead the way on how to debug this? Or what can causing this?

Full log of such behaviour:

[woutervh]

I changed the allocator to use slab in stead of slub, and problems disappeared. So we're doing slab now ;-)

[Bio_TICFSL]

Hello Wouter,

Thanks for the catch, however you might use the yocto community bsp it has a newer kernel.

regards

[woutervh]

I don't prefer to call it "a nice catch" to be honest :-p 

I'd rather find out what the cause is...

A new kernel? For imx53? As performant?

[Bio_TICFSL]

New kernel as avoid those problems with Slub.
