memtest 4.7.3 in grub immediately reboots

[ehall]

I am trying to load memtest 4.7.3 from grub on a local server. Whenever I choose it, the server simply reboots. I know the executable is good because the same file is used with other computers via PXE and they work fine. The same behavior on other computers in the lab.

Memtest86 4.7.3
  root (hd0,0)
  kernel /memtest/memtest

I tried adding the btrace option but its rebooting before it ever gets that far. At this point I assume there is something wrong with the grub statement.

Any advice or input appreciated

V4 is getting pretty old now. V7 is the current release.
We also aren't experts in Grub, you might want to ask the Grub people what's wrong.

Partial follow-up -- with grub2 it works with "linux16" command (instead of "kernel")

Thanks for the follow up, I am sure it will be useful to others.
