Last modified: 2008-08-01 12:22:52 EDT
From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.1) Gecko/20020921 Description of problem: If I hot plug a Firewire device on either of my SMP machines, I get hard locks. This happens every time. Iterestingly, if I plug the device in whilst the machine is powered down, it works as expected. I experienced this problem in the 2.4.10 days. At that time, the problem was caused by dodgy locking in sbp2.c. I haven't had time to investigate in any depth this time round. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. power machine on 2. plug IEE1394 device in 3. paff. Hard lock, no panic, just hard lock. Additional info: Bog standard TI chipset cards, Via based dual processor P3 system and 760MPX dual Athlon MP system.
I have the same problem whether the firewire devices are hot-plugged or are present before power-up. Asus dual-Athlon motherboard using 760MPX chipset, with two 1394 controllers, a generic OHCI card and a Creative Labs Audigy. Three Maxtor drives, two CD-R, and a DVD-R on the generic OHCI card, nothing plugged into the Audigy.
Looks like # 76303 as to the second comment
Thanks for the bug report. However, Red Hat no longer maintains this version of the product. Please upgrade to the latest version and open a new bug if the problem persists.
