winpe hangs with sanhook

[andy_s]

WinPE operates at 1Gb speed if I don't hook the iSCSI volume.
There is no limit on number of sessions on the target, it limits only 1 connection per session. Wth keep-san option the sessions are kept until the target is restarted, so when I restored the windows 7 image on this iSCSI volume, I could boot windows 7 from iSCSI with old sessions being still active.
So it looks like the problem is inside WinPE. Maybe it's Broadcom network adapter and Windows iSCSI, because when I made WinPE image with integrated iSCSI support and booted it (without hooking), I got no network in WinPE.
