iPXE discussion forum

Hi,

I'm trying to use ipxe.iso to boot and install windows 8.1 on pcs with only infiniband NICs.
It works fine with centos7 install, downloading pxelinux.0, initrd.img and vmlinuz from tftp, but when I try to use http transfer for wimboot, bcd, boot.sdi and boot.wim it starts of fine, but after a short while it just stops downloading and nothing more happens.
When I compiled ipxe.iso with DEBUG=infiniband I got the following message:
"IBDEV 0xd22d4 QPN 0x9c048 send queue full"



Any suggestions?

Thanks,
Sigurd

This looks like a possible driver bug. I would recommend you get on IRC and try to debug it together with one of the core developers. In the meantime you can go through the checklist at http://ipxe.org/dev/driver to figure out exactly what is working and what is failing.
