>Description:
Right after selecting "1" at the boot menu to select the default OS install this kernel panic occurs:
    panic: kmem_malloc: entry not found or misaligned

The panic only occurs when EIST is enabled in the BIOS. EIST is fully functional in Windows and RedHat OS's with no problems on this same platform. With EIST disabled the OS installs without issue. The failure also occurs on ia32/i386 kernel.

I noticed that EIST support was first added to 6.0. I tried this version and it also fails. I tried 5.4(no EIST support) and it works fine.

Here's the stack trace after the panic occured:

>How-To-Repeat:
System Configuration:
Intel Bensley server platform
Intel Xeon 5000(Dempsey) processor. Also tried Xeon 5100(Woodcrest)-same failure.
EIST enabled

Boot to the install CD and hit "1" for the default install. Kernel panic occurs within seconds.
