I continue to experience this problem with 2.6.18-mm3. I am about to try building a kernel without ide-cd support. I wonder if anyone else is experiencing system hangs on PowerBooks associated with ide-cd? Thanks, Jack

Since upgrading to 2.6.18-rc6-mm1 from 2.6.13-rc6-mm2 my system started hanging. I copied the below error from /var/log/messages. When my system hangs, it is unresponsive for about 10 seconds, then responsive for 1 second, unresponsive for 10 seconds, then responsive for 1 second, etc. I need to reboot to use my system again. I am not sleeping or waking, suspending or resuming my system. I am only powering down to recover from this error. It happens roughly every 24 hours. I usually wake up to find my system hung, reboot, use it in the morning and again in the evening without problem, but wake to find it hung again next morning. /dev/hdc is my PowerBook's cd/dvd-rom drive. I don't have a disc in the drive when the error occurs, however I've checked the drive and I'm able to read cds. tj recommended using libata/PATA, however I can't find an apple/uninorth/powermac PATA controller config option. Any ideas what is causing this error, why the IDE error handler is getting stuck in a loop, or how to use PATA on my PowerBook?
