I'm having problem with Quad eth100 tulip (digital 21140) cards. The machine was acting as a bridge with kernel 2.2 very reliably. Now, when I boot 2.4.4-ac6, the machine hangs - no oops, nothing. Just hang. even CTRL-Scroll lock does nothing. I supected a bridge problem (I know 2.2 & 2.4 bridge are different) But it's not the case as I reproduce the bug on another machine (with another motherboard. kernel 2.4.4-ac6 where the bridge is not configured.) single boot is OK, ifconfig eth0 up is ok (MII negotiation is OK) ifconfig eth1 up crash the machine - on another boot i tried this : ifconfig eth0 up ifconfig eth0 down ifconfig eth1 up is OK ifconfig eth1 down ... etc etc This works as long as only one interface is up. If only 1 interface is up, the machine works reliably. just putting 2 interfaces up hang the machine. Can this be an IRQ sharing / bridge problem ??? (all interface shares the same IRQ and are after a bridge) I don't know if this is ac-series specific. I'll try tomorrow. Any Idea how I can test further ? Without oops it's not easy...
