[Bug 282840] Re: [regression] WPA not available on ThinkPad T30 (hostap broken)

[Chris Hemsing]

Same here with Intersil prism (1260:3873) wlan device on 9.10.
Detailed information:

a) Standard boot: both orinoco_pci and hostap_pci get loaded
(modules.pcimap really has two drivers for the same device!), orinoco
takes the device: no WPA !

b) Blacklisting orinoco_pci: boot stops (rather stalls forever) when loading hostap_pci with kernel message:
BUG: soft lockup - CPU#0 stuck for 61s!

c) after standard boot: unloading both hostap_pci and orinoco_pci and modprobe hostap_pci afterwards again leads to a system lockup with
BUG: soft lockup - CPU#0 stuck for 61s!
(I first didn't see it, because - of course - you have to wait 1 minute before the first message gets emitted!)

d) With 8.04.1 only hostap_pci got loaded and everything worked fine
with WPA

e) When you blacklist hostap_pci: again it works but no WPA

f) when you manually modprobe hostap_pci with orinoco_pci loaded, this pulls the lib80211 module and the kernel emits
lib80211: common routines for IEEE802.11 drivers
lib80211_crypt: registered algorithm 'NULL'
(this does not seem to be a healthy crypt algorithm ... it might be the reason why using hostap_pci without orinoco_pci loaded fails)
However, the system does not stall.

To summarize: orinoco_pci will not provide WPA (at least not for this
device) and hostap_pci does not work (anymore!)!
