Errors Help need.





Hi,

I'm still having problems with bluez on dev board 82. I've updated the usb-host driver. And then issued hcitool scan to scan for other bluetooth drivers. The error I've got is:
Unable to handle kernel access<1>Unable to handle kernel access at virtual address 02000000

                                        Kernel panic: Aiee, killing interrupt handler!
      In interrupt handler - not syncing
Sorry for the output. This is the best that I've can get from minicom. 
Also when I try write or send to a bluetooth socket, kernel also fails. Here is the kernel output (with old usb driver).

What may be causing this problems, bluez or a bug in kernel? Is there anyway we can fix the problem?

Thanks in advance
