From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.2.1) Gecko/20030505 Description of problem: When disconnecting and then reconnecting an ieee1394 device the kernel hangs on smp systems. This does not happen when using a uniprocessor kernel, the problem is thus likely due to the ieee1394 driver not being smp safe. Version-Release number of selected component (if applicable): kernel-smp-2.4.20-18.9 How reproducible: Always Steps to Reproduce: 1. Connect ieee1394 disk 2. Disconnect ieee1394 disk 3. Actual Results: Kernel hangs, no response, not even SysRq works. Expected Results: Nothing much, at most a message about disconnecting the ieee1394 device. Additional info: The problem does not occur when running a uniprocessor kernel. The hardware is a 2 CPU Dell 2650, 2GB RAM.
