winpe hangs with sanhook

[andy_s]

The LAN is just configured for this case: SLES 11 is Apache, TFTP and DHCP server and iSCSI target with address 192.168.1.100. Both it and the laptop with disabled SATA controller have 1Gb net interfaces and are connected with 1Gb hub.
Anyway I added netX/gateway to boot.ipxe, but nothing changed. I was waiting 2.5 hours - nothing happened.
The boot process is following:
ipxe starts and hooks the iSCSI target. On SLES box, while winpe.wim is extracting, I can see:

Code:

test-iscsi:~/Desktop # cat /proc/net/iet/session
tid:1 name:iqn.2013-03.local.galend:win7
        sid:554270414274624 initiator:iqn.2010-04.org.ipxe:4c4c4544-0050-4710-8037-b3c04f4d5131
                cid:0 ip:192.168.1.150 state:active hd:none dd:none

And the LED on the hub is green (1Gb connection).
After winpe starts, it creates another iSCSI session:

Code:

test-iscsi:~/Desktop # cat /proc/net/iet/session
tid:1 name:iqn.2013-03.local.galend:win7
        sid:600621701333056 initiator:iqn.2010-04.org.ipxe:4c4c4544-0050-4710-8037-b3c04f4d5131
                cid:0 ip:192.168.1.150 state:active hd:none dd:none
        sid:554270414274624 initiator:iqn.2010-04.org.ipxe:4c4c4544-0050-4710-8037-b3c04f4d5131
                cid:0 ip:192.168.1.150 state:active hd:none dd:none

Then afer few minutes it goes to black backlit screen, and the LED on the hub is blinking yellow (100Mb or less connection) every 5-7 seconds. And it lasts for 2.5 hours (I just couldn't wait longer) with both iSCSI sessions active on the target.
