[Bluez-users] OOPS when swsusp/resume when connected to the internet via BT and GPRS

[CIJOML]

Hi all,

today I experienced OOPS when connected via BT/GPRS to the internet, then 
swsup and resumed with dongle in HID proxy mode. Please see details in dmesg 
log:

Restarting tasks ... <6>usb 3-1: USB disconnect, address 3

Any module can change any part of the kernel, e.g. a part of the code 
executed when loading the ath_hal module could accidentally corrupt a 
kernel data structure.

That's wrong, the binary-only blob from ath_hal loaded into your kernel 
is not opensource.

An Oops without any external module ever loaded since booting is 
strongly preferred.

Re: OOPS when swsusp/resume when connected to the internet via BT and GPRS

[Pavel Machek]

Hi!

> today I experienced OOPS when connected via BT/GPRS to the internet, then 
> swsup and resumed with dongle in HID proxy mode. Please see details in dmesg 
> log:

I have had similar problems --but never quite repeatable. I believe I
even have patch somewhere, but I was not able to properly test it.
