I got the same schedule_work problem and I read that redhat had put their own schedule queue in the redhat rpm kernel which caused the problem. Programmer types disabled the kernel schedule queue in the code and recompiled the redhat rpm kernel to eliminate the problem. I discovered that a tarball of 2.4.20 without redhat patches compiled on my rawhide on top of redhat-8.0 system and the schedule_work problem disappeared. Im am no programming expert so anybody that reads this will have some problem of my recollection of the terminology or even what a schedule queue does. kmberry Environmental Lab Tech |
