panic: igc_rxrefill: msix=0 id=351

Hi!

Today I had a reboot on 11.99.5/20260320 because of

panic: igc_rxrefill: msix=0 id=351

I don't remember seeing this one before. Network load was light, there
was a bulk build running and a backup to USB disk.

Backtrace:

Is this a known problem or should I send-pr?

Thanks,
