Ooops, I forgot to mention the hardware config: ASUS P2B-DS,
2xPII, 4-port 100BaseTX (21140).
While we are at it, (AFAIR since 2.3.16-pre1) I see strange messages
in my logs:
Sep 21 10:53:43 lech kernel: PCI: Address space collision on region 6 of device Matrox Millennium II
I set MTRR up at boot, using
echo "base=0xe0000000 size=0x800000 type=write-combining" > /proc/mtrr
echo "base=0xe2000000 size=0x800000 type=write-combining" > /proc/mtrr
Values 0xe0000000 and 0xe2000000 come from my AccelX server output.
