Subject: Re: LKRG is freezing whole software on server installed.

I understand but:
- Do you have the same problem with log_level=0 ?
- If kernel boots (without LKRG) and you load LKRG on already running system 
with log_level=3, do you see the same problem?
- Log file which you've provided is not full kernel log, can you provide full 
one (e.g. there is no LKRG initialization in that log).
- Can you try to repro the same issue with log_level=5 (boot kernel a few 
times until it repro)?

Thanks,
Adam
