Title: Random crash/freeze CPU 100% [kernel{if_io_tqg_N}]
Post by: angled_whacking924 on April 22, 2025, 11:26:32 PM
Hi,

I'm running OPNsense 25.1.5_5-amd64 and have an issue which seems to have appeared from nowhere. Until this, the router has been running seamlessly for over a year.

Randomly every few hours/days the router seems to go slow/become unresponsive and the issue can only be resolved if I physically (as in press the power button) reset it. Rebooting from the CLI or GUI does nothing (though it plays the little shutdown tune).

When I've managed to get onto the webGUI I've found that [kernel{if_io_tqg_N}] is at 100% CPU load. On a few occasions more than one instance of [kernel{if_io_tqg_N}] has been at 100% CPU. N seems to change, it's been 0, 1, 2 and 3 at various times, again seems to be random.

Initially I thought the LAN/WAN was being flooded but I can't seem anything obvious in the logs and likewise I've done a packet capture and there was nothing obvious standing out.

I'm leaning towards a hardware failure but wanted to see if anyone else had experienced this. I can find very little about [kernel{if_io_tqg_N}] both on here and Google.

Thanks in advance!
