Subject: [Linux-ia64] Interrupt redirection problem
Date: Mon, 25 Jun 2001 15:35:07 +0000 [thread overview]
Message-ID: <marc-linux-ia64-105590693005755@msgid-missing> (raw)
This is the output of /proc/interrupts on a Lion that has been up for 9 days:

As you can see, cpu0 is processing the majority of interrupts (91%,
ignoring the SAPIC interrupts). Why?
Andreas.
