From Bugzilla Helper: User-Agent: Mozilla/4.61 [en] (X11; U; Linux 2.2.12-20 i686) Description of problem: While installing, after selecting install mode (upgrade), the kernel freezes such that it is impossible to change virtual consoles.

Adding mem=31M to the boot command string does not alter this.
Could you try "ide=nodma" as option on the commandline ?
This is probably a system on which ide=nodma does not work (we have had one such report before). A network or hard drive install may be required to work around this problem with Red Hat Linux 7.1. Our current source tree has this CDROM drive blacklisted for DMA access, so in future releases this should not be a problem.
