Description of problem:
On a compaq proliant 4500 the installer doesn't see enough memory to run
so I adjusted the memory like I have for previous vers. The kernel panics
with "VFS: cannot mount root device on 8:35". I have 512M in the system so
I started with mem=512M then I tuned it down some knowing sometimes you
have to go 1 less ie mem=511M. Still got a panic. Note: this box is NOT on
the hardware list.
Steps to Reproduce:
1.from installation welcome screen type "linux mem=512M <cr>"
Actual Results: Kernel panic
Expected Results: Installtion should continue as normal with the kernel
being able to utilize all available memory
I have the same problem with a Compaq 2500R.
Ingo: could you add an example of exactmap for a 64Mb machine here ?
Please look at bug 36940 for the commandline option to work around this.
