Subject: [Regression] Bluetooth RFComm: using it locks up the machine
Date: Sun, 04 Mar 2007 09:53:44 -0500 [thread overview]
Message-ID: <45EADD78.1030300@rtr.ca> (raw)
[-- Attachment #1: Type: text/plain, Size: 582 bytes --]
Any attempt to open/use a bluetooth rfcomm device locks up
scheduling completely on my machine.
Interrupts (ping, alt-sysrq) seem to be alive, but nothing else.
This was working fine in 2.6.20, broken now in 2.6.21-rc2-git*
