Description Sterling Windmill 2008-06-16 20:27:10 UTC

Description of problem:

On a system with integrated Intel 82566DM-2 gigabit ethernet, enabling jumbo
frames (tested with an MTU of 9000) results in a kernel panic with the included
version 0.2.0 e1000e driver. 

Installing version 0.2.9.5 of the e1000e driver available at sourceforge
remedies this issue and allows for an MTU of 9000 to be set without issue.

Version-Release number of selected component (if applicable):


How reproducible:


Steps to Reproduce:
1. Run a kernel with the 0.2.0 e1000e driver
2. Set an MTU of 9000 on an Intel 82566DM-2 NIC
  
Actual results:

Kernel panic

Expected results:

Increased MTU

Hi Sterling,

Can you attach the panic output?

Thanks,

P.

It will take me a few days to setup netconsole and find time to force this
machine to crash. I will report back as soon as possible with my results.

Closing as INSUFFICIENT_DATA.
