Have you tried unloading and reloading the kernel module?
The only indication of any issue is an error message that pops up.
kernel: do_IRQ: 7.33 No irq handler for vector.
These messages are usually benign.
I would like to find more details but if I cannot I will just file a
bug
against the kernel.
Have you checked the journal for the time around the resume? Note that
the first chunk of messages at the resume time are actually from the end
of the suspend before the resume.
It would also be useful to know the network chipset. "lspci -v" will
tell you both the chipset and the kernel driver being used. After
resume, try doing "modprobe -r <modulename>", then if that was
successful, do "modprobe <modulename>" and see if that fixes it.
