I have severe intermittent issues with PCI functionality of an AR9280 card. It locks up in a state where it either returns absolute garbage so severe that the kernel plain rejects it, or just mildly garbage data so that it reports corrupt PCI ids. It can fix itself in a running system, so that a later lspci shows the correct device ids and the driver actually loads and runs. I typically get PCI fatal interrupts after resurrecting the card (that takes a couple of power cycles including removing the laptop battery). I don't suppose anyone can explain *in detail* what causee these issues and what could be done to fix them? Finally I've also experienced complete system lockup after a previously working system was left on but idle overnight. All this fun with commit 2d10d8737ccdba752d60106abbc6ed4f37404923 but I believe these problems are nothing new. //Peter -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
