Redhat disabling network interface - IRQ issue
Hi.

I'm having problems on multiple Red Hat VM's (on esxi) whereby the network interface IRQ is disabled by the OS. This is the error from dmesg:

Code:
        command: Write(10): 2a 00 03 42 3f e0 00 00 08 00
mptscsih: ioc0: task abort: SUCCESS (sc=ffff81018b45c680)
irq 67: nobody cared (try booting with the "irqpoll" option)

Disabling IRQ #67

and the interrupts file shows IRQ 67 as eth0.:

Code:

LOC: 4198621982 4198586609

Any ideas how I can troubleshoot this? We experienced a network outage today, and once it came back, we noticed that the NICS on around 5-6 RH VM's had been disabled with exactly the same errors given above. Red Hat v5.5, ESXi v 4.

Any ideas on how to troubleshoot this would be much appreciated.
