Public bug reported: Binary package hint: linux-image-2.6.15-27-k7
Background: I have an MSI Mega 180 form factor pc, which sports an nForce2 MB and has a RaLink 2400 wireless chip embedded. The default rt2400.ko driver supplied with the kernel ('BETA3') loads fine, but consequent iwconfig commands run at 99% cpu and renders the machine useless, forcing a power cycle. Steps to reproduce: 1. Install stock ubuntu kernel. 2. Load the rt2400 module: sudo modprobe -v rt2400 3. Try to run iwconfig: iwconfig ra0 essid any At this point the iwconfig command will never return, just end up using 99% cpu. Ctrl-C, kill -9 etc will also hang. Subsequently, normal shutdowns will also hang. Workaround: Get the rt2400 module from cvs at http://rt2x00.serialmonkey.com/. I'm using the 2006061700 version (although its version line says 2005/07/11. I don't really know why). Compile and install with the usual make; make install. Solution: Ubuntu kernels should not ship with the BETA3 cvs driver.
