Upon installing 6.2 as a relatively standard graphical install (custom install, lilo, 2 ethernet cards[one of them a 4-port], P150, 4GB IDE drive), the system hangs upon the completion of the final package. Everything stays as it was during the package install process. I know that upgrades do work. i.e. If I install 6.1, and then upgrade to 6.2, all is well. I've tried using both the boot disk found on the CD as well as the updated boot disk and updates found in the errata with no success.
Just to confirm, you have tried this errata? http://www.redhat.com/support/errata/RHBA-2000015-01.html
Yes, I've tried with that errata and without. As a side note, there were no problems with a text-based install on the same system.
This appears to be a problem related to this particular hardware. Fortunately the text installer does work.
