I have four 3c905 cards in a firewall/router, each its own IRQ and I/O.
BIOS detects tham all and initializes them, ie., with a hub connected,
all display connection ok. It's an Aopen PII/III mobo, don't have its
version.
Booting Linux, two cards consequently goes dead while network in
started.
Same thing with network restart/reload.
Tried shuffling cards in the fife different PCI slots, no change
(especially since PCI #1 and #5 share IRQ's). Also tried combinations of
Auto and manual IRQ-assignments in BIOS (just to try it), no change.
Tried combinations of three 905C's with one 905B, and half of each;
don't have access to four identical cards. Maybe a problem here?
Tried with only three cards. Som PCI#/card combinations work, some not.
Some stats:
cat /proc/pci |grep IRQ :
Medium devsel. IRQ 7. Master Capable. Latency=32. Min Gnt=10.Max
Lat=10.
Medium devsel. IRQ 9. Master Capable. Latency=32. Min Gnt=10.Max
Lat=10.
Medium devsel. IRQ 10. Master Capable. Latency=32. Min Gnt=10.Max
Lat=10.
Medium devsel. IRQ 11. Master Capable. Latency=32. Min Gnt=10.Max
Lat=10.
cat /proc/pci |grep I/O :
I/O at 0xf000 [0xf001].
I/O at 0x6400 [0x6401].
I/O at 0x6800 [0x6801].
I/O at 0x6c00 [0x6c01].
I/O at 0x7000 [0x7001].
I/O at 0x7400 [0x7401].
I/O at 0xe000 [0xe001].
cat /proc/net/netlink :
sk Eth Pid Groups Rmem Wmem Dump Locks
c1fe29c0 0 0 00000000 0 0 00000000 0
c1fe2700 3 0 00000000 0 0 00000000 0
This is interesting: Netlink shows only eth0 and eth3; 1 and 2, th
troublemakers, don't show at all. I have no explanation...
