Comment 1 Bill Nottingham 2007-09-06 18:24:28 UTC 
Neat. What is your /dev/ttyUSB2?
Comment 2 Zack Cerza 2007-09-06 18:34:27 UTC 
It's "Sierra Wireless MC5720 Modem" - an EVDO adapter. kudzu -p -b serial hangs,
too.

untested patch!

This should theoretically fix it - it tells the rhpxl mouse probe to not probe
the serial bus.
Comment 4 Zack Cerza 2007-09-06 19:42:51 UTC 
I applied this on my running system, and Anaconda now starts properly. Thanks!
Comment 5 Adam Jackson 2007-09-06 21:01:17 UTC 
Looks fine to me.  Applied to rhpxl 0.49, which is headed to rawhide as we
speak.  Serial mouse users are doomed anyway.

In case it's not known, this didn't get into F8 Test 2.
