It seems to be the vblade-kernel module, it just tested it on userspace
version 10, and it works fine - it does exactly what you just said, the
CPU on the other side is working and the pause is consistent - about
7-15 seconds. What is happening with the vblade-kernel is different - it
stalls for minutes at a time, both of the computers have CPU activity at
0%, nothing is happening except the network cards working at 19Mbps
(initiator) and 12Mbps (target).

hmm.. the problem I'm having is not present in the vblade from aoetools
package, it's only with the kernel version.

It works extremely slow with the --sync option (dialup speed).

No problem, here's a bash script I wrote to start vblade, you might find
it handy.
