[Bluez-users] Kernel panic on stopping pand

[Bluez-users] Kernel panic on stopping pand

[Michael McConnell]

[-- Attachment #1: Type: text/plain, Size: 845 bytes --]

Trying kernel 2.6.11.12, I got this (attached) kernel panic message 
after trying to stop pand after the first set of messages logged appeared.

Before that are the messages, when the entire USB layer seems to stall.  
It's possibly worth noting this only happens going through a hub - when 
connected directly to the machine the problem doesn't occur.

There was a second panic, where the machine froze up, and the message 
was way too long to fit on the screen... this wasn't logged in syslog.

It's possible the fault could be the USB hub driver, but it doesn't play 
up like this when I run my USB hard disc through it. I haven't tried my 
DVD burner through the hub - they make expensive beermats :-/

please re-test it with the 2.6.12 kernel. The hci_usb driver is not
perfect, but we had problems with dongles attached to an USB hub before
and so this might be also a problem inside the USB subsystem.
