inpreemptible

Emil,

Config file attached (config-WR3.0.2ax_cgl) 
Hardware config of the target attached with lspci -vvv & dmidecode
output (hwcfg.txt)

Note that get_cpu() is simply a #define to smp_processor_id(), so that
does not matter.

Could you provide the config file? I can't seem to hit this condition
with the latest and 2.6.27 (which WRL is based on?)

Also what HW are you using? (lspci -vvv, dmidecode)

3.0.12 driver is the latest released.

There is only one call to smp_processor_id() in ixgbe_select_queue().
Does the warning go away if you change it to get_cpu()?

Thanks,
Emil
