Too many bugs, too many computers ...
3.12.5-rt7 work ONLY in UP-mode!!! cmdline: nosmp maxcpus=1
In SMP mode, problems arise in different places on different computers. On Intel Atom - USB, webcam and console. On the Opteron 285 system does not boot, can't mount devtmpfs, XFS partitions ...
I can not get to catch the error and find a place neither in debug mode or in normal. Because everything is frozen completely, and get to the console or logs is not possible. I described one situation where had run top and see that the process ksoftirqd/0 use CPU upto 100%
P.S. 3.12.5-rt7 still work Basic-RT mode.
