Not really sure what the problem could be, but there is a BQL fix in 2.4.14. Have you tried the latest driver on e1000.sourceforge.net?

Can you tell us which part you're using as well? Driver is e1000e. Till 1.11.3 it's OK, versions 2.0.0 and later produce the problem. > >How are you configuring the link? Are you bringing the link down with ifdown? Interface is configured with static IP: $ ifconfig eth0 10.1.1.2 up Netconsole is configured as broadcast on that interface: $ modprobe netconsole netconsole=@/eth0,@255.255.255.255/ Link is lost by unplugging of the cable. Event to start the problem could be plugging in the flash disk or similar command to: $ echo "<8>kernel message" > /dev/kmsg Petr >Hello, >I have a problem with usage of netconsole and BQL. >If the netconsole is configured to interface without link and any event (with >netconsole message) happens, the computer starts to print "Reset adapter" >message cca every 2 seconds. >It's because driver watchdog task times out and resets the adapter and >produces new message for netconsole. >Without the BQL, the message is put to tx queue and almost immediatelly >cleared in e1000_reinit_locked. >But with BQL enabled driver, the messages are queued in some upper layer and >are processed one by one with 2 seconds timeout. >Is there any workaround or patch to fix such behavior (to clear higher level >queue in reinit?) ? >Thanks in advance. _______________________________________________ >E1000-devel mailing list >[email protected] >https://lists.sourceforge.net/lists/listinfo/e1000-devel >To learn more about Intel® Ethernet, visit >http://communities.intel.com/community/wired > ------------------------------------------------------------------------------ LIMITED TIME SALE - Full Year of Microsoft Training For Just $49.99! 1,500+ hours of tutorials including VisualStudio 2012, Windows 8, SharePoint 2013, SQL 2012, MVC 4, more.
