I appreciate the effort, but if I'm following correctly I don't b
Hi Jamin,
We value your suggestion, and we appreciate your effort on open source
software and Ubuntu. I am thinking about your words and try to have
balance with debug and cost.
Therefore, I make AMD64 and i386 Jaunty kernel images with generic
config and turning on CONFIG_FUNCTION_TRACER. If it
How else do you propose that a user track down hard to reproduce kernel
panics? If there's a better, more preferred method I'm all ears. I've
been dealing with sporadic kernel panics (hard lock with flashing caps
lock) since just after upgrading to 8.10. Trying to track down the root
cause is wh

Hi Jamin,
Indeed this does not appear to be enabled. The only issue is the kernel
is currently frozen for Jaunty's final release. This may have to wait

the kernel team to decide. Thanks.

Forgot to mention the specific tracing that was missing. The existing
kernels to provide ftrace capability but only some of the tracing

I'm not sure that any of these would help shed light on hard sys
