Description of problem:
While installing, after selecting install mode (upgrade), the kernel
freezes such that it is impossible to change virtual consoles. If I
virtual consoles immediately after choosing "upgrade"" (before the
freeze) then VC3 shows in the last 3 lines:
* going to insmod ext 3.o (path = null)
* looking for USB mouse
* no IDE floppy devices found
The last lines of VC4 are:
<6> raid 5: measuring checksumming speed
<4> p5_mmx : 633.200 MB/sec
<4> raid 5 : using functions p5_mmx (633.200 MB/sec)
<6> raid5 personality registered as nr 4
The installer was invoked with
text nofb ide=nodma
and each time hung at the same point
lspci returns this:

Steps to Reproduce:
1. see above
Actual Results: see above
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.
