#6 debian lenny setserial config causes e1000 network failure

[david graham]

A customer reported an issue to the e1000 developers at http://sourceforge.net/tracker/?func=detail&aid=2834797&group_id=42302&atid=447449, and we determined that root cause was that the setserial configuration for ttyS2 in var/lib/setserial/autoserial.conf , which specifies as IOPORT of 0xEC00:

/dev/ttyS2 uart 16950/954 port 0xec00 irq 169 baud_base 115200 spd_normal

The IOPORT address 0xec00 is, on this system, configured by the BIOS as the IOBar for the "INTEL Ethernet controller: ...Intel Corporation 82541GI...".

The result of this conflict was occassional lock up of the INTEL ethernet NIC. The problem was resolved by removing the ttyyS2 reference from var/lib/setserial/autoserial.conf.

I am not sure whether setserial determines the autoserial.conf setting itself, or if they are provided by some other SW within the Debian distro, but in this case it was definiely invalid and caused the network failure.

If this is not the the proper place to log this report,.then please advise me of where you think the issue lies and I'll move it elsewhere..

Thanks
