FC6 installs and boots erratically on new HP Pavilion notebook

Using a new HP Pavilion DV6040us notebook I reconfigured the HD to provide
three partitions, 75 GB , 39 GB, and 1 GB. The 75 was used to load Win XP
Pro, the 39 to run Fedora core 6 , and the 1GB left alone. The machine uses
an AMD Turion 64 X2 cpu, and FC-6 -X86_64-DVD was used to load the OS.

Two types of problems were encountered. During gui install, the machine
would periodically hang and only a power down could allow recovery. The
hangs seemed to occur at random points in the boot process. I finally did a
text mode install and got things running, but had to boot in text mode and
then do a startx to bring up the gui. On about 1 out of 4 tries the machine
hung, with a blank screen. This feels like a timing problem similar to what
would ocur with overclocking, but this bios has no such adjustment
available.

Windows works fine. No problems have been noted. I am stumped and looking
for suggestions.

Thanks,
Shel
