Subject: rtl8187 usb wifi adaptor causes suspend hang
Date: Tue, 30 Dec 2008 10:51:43 +0000 [thread overview]
Message-ID: <4959FD3F.1060306@tuffmail.co.uk> (raw)
[lsusb: ID 0bda:8187 Realtek Semiconductor Corp]
I'd like to use this wireless adaptor I have, but the driver doesn't
play nice with suspend. 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?

Alan
