Default Bug#589778: linux-image-2.6.32-5-686: prism2.5: hostap loads 90s

Package: linux-2.6
Version: 2.6.32-15 and 2.6.32-17
Severity: minor


After upgrading from Lenny to Squeeze loading the hostap* modules for the built-in prism2.5
wireless network card need ~90s to load (I think loading is done by udev) and thus extend
the boot process by this time. It is quite annoying to have to wait twice as long as the boot
process usually takes, e.g. if the orinoco module for this card is loaded (but no connection
is possible with the orinoco module).

This problem occurs with the kernel versions in testing (2.6.32-15) and unstable (2.6.32-17).
With a vanilla 2.6.34.1 the boot process does not finish because the kernel get stuck in
soft lockups: BUG: soft lockup - CPU#0 stuck for 61s!

Updating the prism2.5 firmware from 1.4.3 to 1.4.9 or 1.5.6 does not help. (1.7.4 does not
help either and prevents the card from connecting.)

Blacklisting the hostap* modules (the orinoco modules are already blacklisted by the
hostap-utils package) prevents all modules from loading which dramatically decreases the boot
time. Manually loading the modules shows a bunch of messages in dmesg (which do not help me
finding a solution), it still nearly completely block the whole system (but top does not show
any number significantly above 0% except idle) and a connection is not possible.
