Interrupts issues

2008-09-19 Thread Benjie Chen
Hi FreeBSD hackers: I have two Dell workstations that I recently added FreeBSD 6.2 on. One is a Precision T3400, one is an Inspiron 530. Nothing fancy. Installed FBsd. Everything else is fine except both machines have interrupt storm issues: one core (both dual core) is 100% servicing interrupts.
