[PlanetCCRMA] rt kernels, ho, ho, ho!

I too cannot seem to boot the rt kernel for Fedora 14. I have a fresh 
install on an older Dell Inspiron 1150 laptop, with a P4 2.8 GHz CPU. I 
couldn't figure a way to see where it was hanging, so thanks for the 
tip. I thought that is was hanging at loading cups.

It appears to be hanging after loading the firmware for the on-board 
Broadcom wireless card. Here are the lines prior to it hanging:

b43 ssb0:0 firmware: requesting b43/ucode5.fw
Starting cups: b43 ssb0:0: requesting b43-open/ucode5.fw
b43 ssb0:0 firmware: requesting b43-open/pcm5.fw
b43 ssb0:0 firmware: requesting b43-open/b0g0initvals5.fw
b43 ssb0:0 firmware: requesting b43-open/b0g0bsinitvals5.fw
b43-phy0: Loading OpenSource firmware version 410.31754
b43-phy0: Hardware crypto acceleration not supported by firmware
b43-phy0: QoS not supported by firmware

This may be a problem with this "open" firmware. Maybe a copy of the 
original "proprietary" firmware will work. I'll see if I still have a 
copy laying around. I'll also try blacklisting the b43 module, to see if 
it boots. This is not a solution, just a test.
