linux boot hangs with grub

[Simon J. Rees]

I have W2K and Redhat 7.1 on a new system. Redhat put lilo in the MBR but I
would like to use grub to make a dual boot setup. I have compiled grub-0.90
and used grub-install to make a grub boot floppy. Using the floppy I can get
the grub console and I can boot W2K fine. To try and boot linux I used the
following commands at the grub> prompt:
root (hd0,4)
kernel /vmlinuz root=/dev/hda7
boot

The system will start to boot linux but will hang when it gets to starting
kswapd. The last message is 'starting kswapd v1.8'. The system will boot
linux fine using the lilo setup by the redhat installer. Any ideas?

Thanks,
Simon
