PREEMPT_RT with e1000

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



It looks like Gigabit Ethernet is still having some problems. This is
with the e1000 driver. If I remove all the qdisc_restart changes it
starts to work the warning below goes away, but it has smp_processor_id
warnings.
