I can not provide calltrace because some other warning/traces show up instantly after the problem happen and mask prints for initall problem. Then the machine hungs. Anyway bisection blame b11e19694dc9 commit and I confirm that problem not happen before this commit. I also applied the fix with I just posted, so this is diffrent issue. Thanks Stanislaw
