I'm running a slightly modified 2.6.16.13 kernel on FC5-amd64. The

site,
the PCI-X slot is 133Mhz. I'm using a 4-port pro/1000 NIC.
dmesg shows a listing of 120Mhz:

ethtool -d eth3 shows 66Mhz:
....
0x00008: STATUS (Device status register) 0x00003B87
Duplex: full
Link up: link config
TBI mode: disabled
Link speed: 1000Mb/s
Bus type: PCI-X
Bus speed: 66MHz
Bus width: 64-bit
Any idea why I see the slower bus speed reported?
ethtool currently doesn't know about some bus speeds, and will report a wrong
speed. Here's what ethtool currently uses: (ethtool-3/e1000.c)
327 (reg & E1000_STATUS_PCIX_MODE) ?
328 ((reg & E1000_STATUS_PCIX_SPEED_133) ? "133MHz" :
329 (reg & E1000_STATUS_PCIX_SPEED_100) ? "100MHz" :
330 "66MHz")> :
obviously 120 is missing, but PCI-E speeds are also missing (2500gbps). The
output of the e1000 module is correct.
