If so, which?
kernel 2.6.24 version 4.44.1.20 of the firmware. The iwl4965 version is fairly ancient in mainline kernel: 1.1.17kds Last time I looked, 1.2.24 was the latest version, but I never succeeded in getting it to work (or compile?) in 2.6.24. Don't know whether it's a regression - I've only been excercising my wireless recently, although I'm sure I would have come across it before when I was using 2.6.23 (which also comes version 0.1.15kds of the iwl4965 module, by the looks of it). Haven't rebooted yet since this problem began, just in case this is just a temporary problem that needs debugging. -- Tim Connors -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
