Description jan 1998-11-16 00:31:16 UTC

The boot floppy for the RedHat 5.2 installer contains a
vmlinuz image that crashes my new machine.

Machine Details:
	Tyan S1836DLUAN-GX motherboard
	Dual PII 450MHz
	1GB RAM
	9.1 GB Ultra SCSI western digital hard drive
	Diamond Viper 550 video controller

Boot message:
	...
	calibrating delay loop.. ok - 450.56 BogoMIPS
	initrd overwritten (0x00e00000 < 0x01014e34) - disabling
it.
	Memory: 1032740k/1048576k available (708k kernel code, 384
reserved, 14744k data)
	Bad pmd in pte_alloc: 008000e7
	Kernel panic: Failed to allocate buffer hash table

	In swapper task - not syncing


Note:

The boot floppy for -> RedHat 5.0 <- does not
crash the machine, but I want to install RedHat 5.2

Found workaround.  It appears the kernel will not boot with very large
memory sizes (such as 1GB).  Giving the following parameters works:

linux mem=1008M expert

This problem should be fixed in the latest 2.0.36 final release. Try
downloading the new 2.0.36 rpm when it is made available and try this
one again. If yes then please close the bug report.
