Using the latest 2.6.13 kernels in FC4 on a Sun dual opteron workstation, I am seeing an error at boot time that doesn't happen under older kernels. Oct 3 11:21:48 diego kernel: MEM window: d0200000-d02fffff Oct 3 11:21:48 diego kernel: PREFETCH window: disabled. Oct 3 11:21:48 diego kernel: PCI: Failed to allocate mem resource #6:20000@f0000000 for 0000:09:00.0 This appears to be a non-fatal error at first glance but is worrisome. Has anyone else seen this problem and is there a fix of any sort? Jack
