Hello guys,
Those of you old enough will remember the problem I reported in 2000 (and at the time fixed) with quad Xeon SuperServer8050 machine, here is the message from 12 October 2000:
http://www.uwsg.iu.edu/hypermail/linux/kernel/0010.1/0789.html
Now, something must have changed between 2000 and 2004 because exactly the same problem came back now when running 2.4.21-4EL kernel from Red Hat Advanced Server 3 distribution. Only now, disabling the caching of CXXX areas in the BIOS doesn't fix the problem, unfortunately. I haven't tried 2.6 on that machine, because I need to get it working urgently with AS3 kernels.
Did anyone else run into this? Maybe I should upgrade the BIOS which will tune the caching in the chipset appropriately? It is an S2QR6 motherboard with 4x PIII Xeon 700MHz and 6G RAM, AMI BIOS v1.2 (not upgraded since 1999). The problem is that "everything" is about 40-50 times slower than normal. E.g. gzip -9 of a 10M random file takes 6 minutes instead of 5 seconds etc. It used to compile the kernel in 50 seconds (as the message above says). Now it is taking ages, so slow not even worth mentioning the exact numbers (i.e. unacceptably slow!)
Kind regards Tigran
