[rhelv6-list] Red Hat 6.2 update woes

[Bill Watson]

Howdy,

I installed RHEL 6.0, then "yum update"ed to apply all patches. This 
fouled my new kernel (2.6.32-220.7.1.el6.x86_64) with the following:
[drm:drm edid_block_valid] *ERROR* EDID checksum is invalid, remainder 
is 88 (repeated 3 more times) [drm] nouveau 0000:06:00:0 DDC 
responded, but no EDID for VGA-1 Kernel panic I have a GdForce 8400GS 
IO Express 2.0 graphics card w/DDR3 I got the system back up by 
booting the original kernel (2.6.32-71.el6.x86_64).

There is no mention of RedHat on the video card website wvga.com in 
the driver section. Is there a glimmer of hope that this card can work 
with RHEL 6.2?

Upon further research, I tried booting the kernel, and at the choose which
kernel screen, added: nomodeset edid_force_checksum=1 nouveau.modeset=0
This removed display of the EDID checksum errors, but still kernel panic'ed
with the dreaded:
kernel panic - not syncing: Attempted to kill init!

All the helpful hinters said to check /var/log/* and this seemed to be
unhelpful since "not syncing" seems to also mean "not writing useful
stuff onto the log files". It is possible that though the following Adaptec
card can read enough to boot, it doesn't see the filesystems when the
kernel takes over.

Also I have found that the Adaptec 6805 RAID SAS/SATA card is tough to 
install. I did find a path where installing RHEL 6.0 does work. I have 
found no path to install 6.2 directly. For quite a while I have found 
Adaptec to be basically native to Red Hat, but this card is hostile to 
install.  As far as that goes, I got RHEL 5.5 working, but not 5.8 for
installation.

I saw a mention of  kmod-aacraid-1.1.7-3.el6.elrepo.x86_64.rpm  over on
Dag's
http://elrepo.org/linux/elrepo/el6/x86_64/RPMS/ that sounded really tempting
to install, but I don't know if it would blow up my working original kernel
or not.
Until I am confident of a direction, I'd kind of like to keep this kernel
working
so I can continue to try this and that.

Thanks all in advance,
Bill Watson
