Re: [BUG] NULL pointer dereference probably caused by kernel/trace/ring_buffer.c

[Roland Ruckerbauer]

Just figured out something, the poll() errors starting at fd 29 (which
is CPU 24).
But I only have 24 cores. Looked at
/sys/kernel/debug/tracing/instances/rasdaemon/per_cpu/, and voila, it
lists 32 cpus not 24.
