Is anyone else having problems with the current 2.6.24.5-85.fc8 kernel and kmod-fglrx-2.6.24.5-85.fc8-8.476-2.8.04.lvn8.x86_64? Our workstation with a Dual Core AMD Opteron(tm) Processor 175 on a Tyan S2866 Tomcat K8E-SLI and ATI Radeon X1650-Pro graphics card is constantly rebooting. The message log shows...

[X:2977] May 1 16:26:52 bromo kernel: CPU 1: This problem doesn't occur with the stock radeon drivers in use. I've tried passing noacpi, noapictimer and acpi_use_timer_override to the kernel without success in suppressing this problem. Thanks in advance for any advice on this problem.
