Network interface configuation (e100) locks after some time
Last modified: 2006-01-24 00:58:46 UTC
Noticed on a Toshiba Latop Portege M100. lspci lists the device as "Ethernet controller: Intel Corporation 82801DB PRO/100 VE (MOB) Ethernet Controller (rev 83)". The module is e100. Symptoms: After running some time (10min to 30min) the interface locks up configurationwise. Any "ifconfig eth0" will lock up. kill -9 (or any other signal) on the ifconfig process will have no effect. Shutting down the system will lock when reaching the point to unconfigure NW-interfaces. The interface is configured with DHCP, it stays accessible, just the configuration locks up.
Which interrupt is being used by the NIC? Is it shared with some other device? Does the problem also happen when you boot in "failsafe" mode?
irq 11 along with just about everything else (eth0, USB -ehci and uhci-, 1394, ICH4, yenta, ipw2200). apparently the problem ceases in safe mode. I waited 60 minutes now, but ifconfig still works...
Ok, some progress. "Failsafe mode" means several parameters are passed to the kernel. Could you please try to find out which one of them makes the difference? You can do a binary search, so it should not take more than two or three iterations.
If ifconfig locks up this may really mean there may have been a kernel oops. Please run hwinfo and attach the output to this bug report. Please also check your system log (/var/log/messages*) for Oops messages.
No feedback close it for now.
