Hello,
I'm trying to get my T30 laptop with the standard built-in intersil prism 2.5 wavelan wireless card to work with WPA2 authentication.
I have flashed the firmware of the prism card to v1.8.4 (see http://junsun.net/linux/intersil-prism/), and this was working correctly for me in early Jaunty releases, but with some patch or other it now does not work.
The standard workaround (<http://ubuntuforums.org/showthread.php?t=446010>, <https://help.ubuntu.com/community/WifiDocs/Device/IntersilPrism25Wavelan>) is to blacklist orinoco and associated modules so that the hostap modules will be used to interact with the card. This workaround appears to be standardized now to the point that if you install the optional hostap-utils package via synaptic then it will create an /etc/modprobe.d/hostap-utils.conf file which blacklists orinoco and associated modules.
As stated, this all worked for me in early Jaunty. As of a patch to Jaunty a month or so ago, and still with Kosmic, it now causes my machine to hang whenever the hostap module tries to talk to the card. From a practical standpoint, this means that if I blacklist the orinoco drivers (per the workaround) then the machine will no longer boot. If I leave them un-blacklisted, but attempt to remove them via rmmod, and then re-load hostap with modprobe, the machine does a hard hang and will no longer respond.
This happens on two different T30 laptops (I bought a second one assuming that the first had some kind of hardware problem), so I suspect it is a kernel bug and not a hardware error.
Any help would be appreciated.
Standard diagnostic info and command output is below, though note that this is the pre-workaround status, with both orinoco and hostap modules loaded, and orinoco is the one that has grabbed the wireless card.
