Hi,
We have a system running 2.4.17 with the following configuration.
------North Bridge---------PCI-PCI-BRIDGE----82559ER
|
82559ER
# lspci
......
00:12.0 Ethernet controller: Intel Corp. 82559ER (rev 09)
.......
00:0f.0 PCI bridge: Digital Equipment Corporation DECchip 21152 (rev 03)
.........
02:01.0 Ethernet controller: Intel Corp. 82559ER (rev 09)
#insmod eepro100
.........
eth0: Intel Corp. 82559ER, l00:eC0:s85:/30:292:.9F, 4IRQ 12.
............
eth1: OEM i82557/i82558 10/100 Ethernet, FF:FF:FF:FF:FF:FF, IRQ 10.
........
It seems eepro100 driver can't read the eeprom from the 2nd card. I
have
printed the data bits in the
do_eeprom_cmd routine, all were 1. Adjusting the delay did not help.
The eepro100 driver on 2.2 kernel works fine and even intel's e100
driver on
2.4.17 also works fine.
I guess there may be some timing issues involved.
Are the devices beyond a bridge imapped to I/O space properly in 2.4
kernel? Intel's driver reads the EEPROM
control register using memory cycles.
