RE: Errors Help need.


There is nothing we can read from these traces. The numbers printed
corresponds to your build so they need to be decoded in your tree.

I got the decoded traces from you but they look totally screwed up.
The output from ksymoops should look something like this:

[<c016ffe3>] iput+0x63/0x80
[<c8ae9c27>] usbdev_release+0xb7/0xc0 [usbcore]
[<c0157a5c>] __fput+0x10c/0x120
[<c0156047>] filp_close+0x57/0x80
[<c0123d17>] put_files_struct+0x67/0xd0
[<c012491e>] do_exit+0x15e/0x3e0
[<c0124c4a>] do_group_exit+0x3a/0xb0
[<c02a302e>] sysenter_past_esp+0x43/0x65

(this example from an Intel but your output should look similar).

Can you try to only copy-paste the output from Oops until not syncing 
to ksymoops?

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:

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
