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. On the Precision, it's irq20 atapci, on Inspiron it's irq19 uhci. The other core is fine and both machines run well otherwise. I saw several recent posts on the net about some of these issues and did not find a resolution. It seems unlikely that it's just a ata or usb issue since both machines happen to have the same problem. Any thoughts? Thanks, Benjie
