A interesting thing that i found out is that when the agent is reset =

Looks like during agent reset your SRIO link becomes good and host's =
requests go ahead.
After that you get a machine check (response time out): link is OK but =
agent is not configured.

Can you check/print 0xC_0148 and 0xC_0158 registers of SRIO block before =
the first maintenance read.
