Hi
I confirm the issue. On a custom UEFI firmware based on UDK2010.SR1 (or EDKII head), UEFI PXE boot fails with grub2 (release and latest version).
If I enable only the IPv4 stack in the firmware and the old PXE BC driver, it works most of the time. I sometime have "Not an IP" or "couldn't send packet" when I download a linux kernel...
If I enable both IPv4 and IPv6, and the new PXE BC code, it doesn't work. As Lingzhu Xiang explained, the IPv6 stack sends icmpv6 messages which gets into a race condition. This can easily be observed with wireshark. An incoming icmpv6 message during a file transfer will stall it.
For your information, the problem doesn't occur with Elilo. Elilo uses MTFP protocol and it always works.
Regards,
Thomas
