Message: 99822   

I'm currently (rarely occurring) seeing an kernel crash on the 524 with the following dump. Attached is my kernel config. I'm running the 2010RC5 kernel. Has anyone else seen this issue?

that config isnt useful.  please run `make bugreport` and post the tarball as an attachment.

do you have any custom drivers running ?  what devices/drivers are you using when things fail ?

We've also seen the following crash which looks very similar to   blackfin.uclinux.org/gf/tracker/6465. Could these be related?

i think the workqueue bug is different.  that is being tracked here:

  blackfin.uclinux.org/gf/tracker/6465

it would be good if you could remove driver/device usage from the system to try and narrow down the problem.  we havent seen any bug's in the timer code so far.

i dont understand why you have a custom bfid.c driver.  you can already read the OTP memory with the bfin-otp driver and reading /dev/bfin-otp.
