Thanks! I never noticed this test program.
From "scanpci -v"
Adaptec 2940U/UW
MAX_LAT 0x08 MIN_GNT 0x08 INT_PIN 0x01 INT_LINE 0x0b
Digital Equipment Corporation DC21142 10/100 Mb/s Ethernet
MAX_LAT 0x28 MIN_GNT 0x14 INT_PIN 0x01 INT_LINE 0x0a
It looks like the adaptec is already set for a conservative number in
my bios. I guess something is just using up too much pci bandwidth.
I wonder where the BW is going. NFS tars which is where I see the
starvation only runs at around 1MByte/sec.
I also note that the kernel says the quad-port dlink has 4 DC21143's,
yet scanpci claims they are DC21142.
