Hi all,
Hi,
Not sure who I should be talking to about this, but we're hitting a weird
issue with kernel-rt-3.10.0-957.12.2.rt56.929.el7.src.rpm from CentOS.
3.10-rt56 is terribly old and unsupported [0].
Unfortunately I'm stuck with CentOS kernels in the near term.
Anyone got any suggestions on where to start debugging it? Kernel options
to enable, extra debug logging, events to monitor?
You could try to enable MM debugging, lock debugging and so on.
Thanks...I've enabled CONFIG_PROVE_LOCKING, hard/soft watchdog, and
netconsole. Hopefully I'll get something. :)
Chris
