X-BeenThere: freebsd-hackers@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: Technical Discussions relating to FreeBSD List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Fri, 08 Aug 2008 18:43:01 -0000 this is an interrupt handler that's attached to irq 31 on ioapic1 on a 6.1R kernel, type INTR_TYPE_NET|INTR_MPSAFE. seems that it's missing interrupts. watching the KTR trace, it was running along fine, then it just stopped. intr handler stopped getting run. but the interrupt register on chip was high. is this a case of lost interrupts? or hardware problem? TIA, ping
