I got an "SMC SMCWPCI-GM" card the other day, which is one of these: May 27 01:16:55 router kernel: ral0: mem 0xf4000000-0xf4007fff irq 10 at device 13.0 on pci0 May 27 01:16:55 router kernel: ral0: MAC/BBP RT2661D, RF RT2529 (MIMO XR) I put it into a Pentium III machine (which has PCI 2.2, per the ral(4) man page) running a 7-CURRENT build from earlier today with a GENERIC kernel, and attempted to connect to my wireless network, the access point of which is an Atheros 5212 card, which has been serving Prism and other Atheros cards for months. The RT2661 card associated fine and was able to carry out lightweight operations like pinging and HTTP requests, but when I attempted to use it to send or receive any heavy traffic (a few dozen KiB/second), the system froze. I was able to toggle the caps lock/num lock lights, and if I did something to make the system beep (i.e. by pressing ALT+F10 when there was no virtual terminal running there), the beep would ring out endlessly. It may also be worth mentioning that the system was unresponsive to ACPI (via the power button) and that the same RT2661 card in the same machine has no trouble sniffing over 2 MiB/second of traffic via tcpdump. I'll be happy to provide any other information that may be deemed useful. Thanks. -Boris
