There's one more thing I forgot to mention; deinitialization does not seem to work correctly. If I remove the mantis driver and reload it, the CAM is no longer detected correctly (when the 50211 driver tries to read the identification bits from the CAM memory space, they simply don't match anymore). This is annoying, as it means a reboot is required whenever one wants to test a new fix, but I haven't been able to figure out why it happens. Just wanted to mention so that nobody bangs their head in the wall too much due to hitting that problem :-) /* Steinar */ -- Homepage: http://www.sesse.net/
