Subject: PREEMPT_RT with e1000
Date: Wed, 31 Aug 2005 13:03:22 -0700 [thread overview]
Message-ID: <1125518602.15034.3.camel@dhcp153.mvista.com> (raw)
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.
