[ale] Upgrade hell

[Cor van Dijk]

Greetings,

For years I had RH 6.2 running on my Sony laptop without any problem.
To get usb support I tried to switch to RH Enterprise 3.3  (which is 
running fine
on a regular PC.) Halfway through the setup process I am told that  the 
machine
- that is the laptop - is not supported.

Then I tried to upgrade using  RH 7.2, which has been running for years 
on a regular
PC without ever any problem. That upgrade  worked. However, every now 
and then
I get a hang when in an X screen; it does not do that in a startup console.

I then tried a complete reinstall of RH 7.2, reformatting all partitions 
and checking for bad blocks, but with the same result: hangs!
I ran a memtest for several hours: zero errors. No interrupt conflicts 
that I can see.

It appears that there is a bug in the X-machinery or maybe in the Gnome 
stuff.
Anybody seen this? Any fix?

Any help is appreciated, Cor van Dijk.
