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.
