I have a newly built drive with 5.2 fresh install (that I will be
cloning shortly) in my DECtop and it is failing with X the same way the
upgrade from 5.1 drive did (not too supprising there).
In 5.1 X worked. I could startx from init 3 and get into GNOME. Also
VNC into the box and have a GNOME screen. With 5.2, I get a kernel
panic. Well I guess it is a kernel panic because once I run startx from
the console, my SSH session to the box from my notebook is frozen.
From /etc/sysconfig/hwconf I have:

bus: PCI

Processor"

Now the way I got this working in 5.1 and 5.2 (5.1 install died for some
reason or other, forget which and for 5.2 this unit has the powerk8
patch requirement), I install on an old compaq and change to init 3. I
then move the drive and run system-config-display to get the unit to
read the hwconf file and reset xorg.conf. This worked fine in 5.1. In
5.2, the system hangs. What to do? btw, i tried pci=noapci with no change.
A couple other facts about this system. No accessable bios. When the
system is booting (in character mode) the video frequently goes off then
back on; some refresh problem. I have also seen this at times in a
session on the console when I enter some commands. It would be nice to
fix this. It might also tie in with the X problem.
Thank you for your continued help.

Nope...

I added --set-depth=16 --set-videoram=0 and still failed.> >>> also, you can boot the older kernel from 5.1 and see if that helps. >> I did try that on the system I upgraded from 5.1.

I am using the vesa_drv.so driver. This works just fine on 5.1. In the Centos 5.2, this driver is unchanged. Same date and filesize. Now a number of the video driver files are unchanged from Centos 5.1, but Generic VESA compliant is how Centos is handling the National Semiconductor Geode video in my DECtops. I noticed there is a vesa.h file with a filesize of ZERO. But in the case of the system upgraded from 5.1 to 5.2, it had this file for the 5.1 kernel as well as for the 5.2, so I don't think this is important. One more fact: When I do a startx, I see some messages, but they are not written to any file I can find, nor are they visible when the system hangs. Other oddities about this system. It has 2 sets of 2 USB ports. In 5.1 you MUST have the KVM USB keyboard plugged into the USB port labled for the keyboard (otherwise no keyboard detected). This is not necessary for 5.2. But if you put the keyboard into some other USB port (say the one with the printer icon), if you do not have the KVM 'focused' on the system while it is booting, it appears hung with no video (for either 5.1 or 5.2 if it is plugged into the keyboard USB, it can boot while the KVM is 'focused' on another system). Wierd.
