Any update on this? I'm having the same issue with an HP DL360 G6 machine. 
When booting PXE ROM -> ipxelinux.0 -> vesamenu.c32 -> ipxe.lkrn 

I'm doing it this way because after the ipxe.lkrn i'm chaining to sccm, and the ipxe.lkrn sets the user-class different so that we can have the dhcp point to a new next-server (wds) when ipxe.lkrn does the second dhcp.
But that second dhcp is never done goes of the above error 'Try to free Memory without Signature'.

Any way to try out the new bnx2 driver in the above method of booting, to work around this issue?
