Re: [E1000-devel] Problem with Linux 2.6.32 and e1000e
Hi Emil, It appears as if updating to the latest BIOS fixed it (the previous BIOS was almost a couple of years old, there just hadn't been a reason to update it). The events thread is no longer stealing the cpu with any of the e1000e-1.x drivers. Thanks for the suggestion. I have attached the output of ethtool anyway. There were no specific patterns with the issue, it would start as soon I loaded the module and brought up eth0. I still haven't tried with the link connected, and if that happens to cause problems when do I get a chance to test it, I will let you know.

I am curious about the error messages you are seeing. Do you know if you are running the latest BIOS? Maybe check for updates. Do you have AMT enabled? Maybe try enabling/disabling it and see if it would make a difference. It is enabled on my system. Also if you could provide the output of ethtool -e eth0 that would be great. I will continue to play with my system and see if I can get a repro. Have you noticed any patterns - for example does it matter if the system is running on battery vs. power. Also you mentioned that you don't have cable connected - do you see the same spikes when cable is present?

Re: [E1000-devel] e1000e not working on 2.6.29.1
Jesse, Before I got your reply, I had recompiled my kernel a couple of times in the hope of getting wireless to work at least. However, I also removed some other stuff from the kernel that I didn't need, and now e1000e works and I don't see anything unusual in dmesg. Unfortunately, I can't pinpoint which feature's addition/removal caused it to work. I mostly changed features for getting the iwl3945 driver to run. Looking at the kernel config again, the only thing I can think of that I may have removed is CONFIG_X86_REROUTE_FOR_BROKEN_BOOT_IRQS but again, there may have been something else. Apologies for the confusion, and perhaps I'll try again with the above option and see if it reproduces the problem.
