[ipxe-devel] undi ipxe taking 100% cpu under vmware when boot server is offline

[lustu.starrysky.cru at gmail.com]

Hi all,

   I am running ipxe with UNDI driver under VmWare (don't know if the driver
matters at all).

I consistently see it taking 100% cpu under even when boot server is
offline.

Searching through the source code I see that cpu_nap() is being used exactly
for making sure ipxe doesn't take 100% of the guest cpu while waiting, which
would be too much of the host cpu.

Is there any place where ipxe is still doing busy waiting?

thank you!
