Greetings, I recently upgraded from 2.4.20-24 to 2.6 Test 11 using a Redhat distribution. Got everything up and running great, except the entire system appears to freeze (requiring a hardware reset) when I disconnect my bluetooth device. I am using a Thinkpad T30, which has an integrated USB-based Bluetooth card with a little power switch to activate/deactivate it. I can turn it on and it'll work fine, see devices, etc., but every single time I turn it off, the laptop freezes. Did not happen with the 2.4 kernel. I am using the bluetooth stack provided by the Kernel along with the configure scripts and such from the Bluez package. It does not appear to be a "bluetooth" issue, however - it seems more related to USB to me. Anyhow I thought I'd fire off an email. I'd be glad to supply more specific information - just tell me what you need. I am able to reproduce this every time so shouldn't have a problem determining what might affect the situation in a positive way. Compressed copy of my .config included Jonathan
