Description Michael S. Fischer 2000-02-19 02:13:54 UTC
I've tried to rebuild the stock 6.1 kernel RPM for 2GB RAM support by
replacing the kernel*i686*config files that are provided with the kernel
(changing CONFIG_1GB=y to CONFIG_2GB=y) and rebuilding the binary RPMS.

However, after installing the new RPM on a test system, the kernel refuses
to mount the root device, because the initrd is clobbered at boot -- the
following message appears:

kernel: initrd overwritten (0x80fb4000 < 0x815ba04c) - disabling it.

It's imperative you look at this before 6.2 is released, or that you
document that 6.2 does NOT support 2GB RAM configurations.

This is resolved by using the enterprise kernel which contains BIGMEM support
for >1GB.
