I notice Jiri, in your hardware list, you have an ath5k Atheros AR5212 chip
in there.
I took a look at the resume code for ath5k but nothing really suspicious
there except:
err = pci_enable_device(pdev);
if (err)
return err;
pci_restore_state(pdev);
Shouldn't we restore state before we turn the chip back on and thus
potentially let it start DMA'ing all over the place?
Hmm, actually every second wireless driver do this :/. I think it's wrong too.
Jesse?
BTW pci_set_power_state(pdev, PCI_D0); in resume isn't needed at all, right?
It's done in pci_enable_device, isn't it?
