Hi
On one of my machines with tickless kernel and plip I get messages :
I bet this is a machine a P4 with Hyperthreading enabled ?
No, it's single Pentium 2. I have other Pentium MMX using plip, where I
don't get these error messages, I don't know why.

NOHZ: local_softirq_pending 08
always when using plip (on other machine with tickless kernel and plip I
get no errors). Thebug happens both on 2.6.21 and 2.6.22-rc1
This patch fixes that. Note that plip calls netif_rx neither from hardware
interrupt nor from ksoftirqd, so there is no one who would wake
ksoftirqd then. netif_tx calls only
__raise_softirq_irqoff(NET_RX_SOFTIRQ), which sets softirq bit, but
doesn't wake ksoftirqd.
Dave,
can we please get rid of __raise_softirq_irqoff() at all ? These micro
optimizations are causing more trouble than they are worth.
tglx
