I've since updated the kernel several times (the latest update being just last friday), but the problem hasn't disappeared so far. I get an oops, followed by a reboot when wpa_supplicant has associated an if_ral interface (which is a removable PCMCIA Ralink based WLAN card) when powerd is running. As soon as I disable powerd for my laptop (and it runs continuously at 1800 Mhz), the oopses disappear. As I'm getting a kernel oops, if anybody is interested, I'd more than happily reenable powerd to produce a kernel dump and make that available to anybody who is interested in debugging it, along with the kernel images, of course. I'm running a self-compiled GENERIC (with nothing changed except for the self-compiled part). I currently don't have the time to track this down any further myself, though, and the workaround works for me.
