Haven't had much luck with betas on RBs; thought I'd try a PC platform. Took a working lastest stable and applied RC6.

All interfaces now cease to function with "Disabling IRQ#" for each of the three. They still show up under /irq and /eth as valid.

Did a downgrade via iso to 2.9.48 with "keep configuration"; back to working router now....

Tell me more about 'Disabling IRQ#'?

Is this a BIOS or RoS function? I've been trying to find som way of balancing IRQ's in RoS. I find it becomes quite a problem with shared IRQ's on interfaces passing traffic, particularly if shared between LAN & WLAN.
