It hangs after switching to the console, without printing anything. This happens even if I haven't used the adaptor (i.e. ifconfig shows 0 bytes rx/tx). Interestingly the numlock key on my USB keyboard still works. I tried "no_console_suspend nmi_watchdog=1", but it didn't show any more output. (I waited 3 minutes for the watchdog to trigger). However, I can insert panic() calls, and see whether I hit the hang first, or go into a panic with flashing keyboard LEDs. I used this to confirm that the hang happens inside the rtl8187_disconnect() function. There's a good chance I can track this down myself, using panic() again. Before I start, does anyone have an idea what might be happening? Ta Alan
