Content-Type: text/plain; charset=us-ascii; format=flowed Content-Transfer-Encoding: 7bit Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org I've just run in to a similar problem with 2.4.20. The system hangs using 2.4.20, and everything is fine with 2.4.18-10bigmem (rh73). Points of similarity: Dual (SMP) P3-450, supermicro (BX) motherboard kernel 2.4.20 red hat (7.3 w/ updates) Differences: no IDE main disks on AHA2940U2W Firewire (aua-3121) or scsi AHA-1542 I've found two separate hangs. The most interesting is that I have two (different) firewire disks. I can access either of the disks all day, but as soon as I access both at the same time the system hangs. I am unable to test this on 2.4.18 as one of the firewire disks (WD 200GB) is not recognized correctly under 2.4.18, which is why I am running 2.4.20 in the first place. The second hang seems related to ejecting an audio cd-rom from a CD-RW attached to its private AHA-1542 scsi controller. Both hangs are "hard" without any sort of output to the console. I also lose the console echo. I'd guess that I'm running into a SMP deadlock. --- Matthew Costello
