A lot of these machines have had this problem in one form or another since
upgrading them to 2.4 kernels. On 7.2 systems for instance running the smp
kernels on UP machines worked around it for us. On 8.0 I have actually had
to compile a slightly modified version of the Red Hat kernel to get them to
boot. The problems with this chipset are well known. Bugzilla has numerous
entries in it for this problem. I wish I understood things better but this
seems to be the way things are. :-( It is trivial to recompile the kernel
to get it to work. The only problem is doing so appears to break compatiblilty
with numerous laptops so Red Hat will not fix it at the cost of breaking
the laptops. :-( FYI the above information is documented in bugzilla.
