Hello,
This note is just a heads up to avoid duplicating our efforts. We are working
on capturing the registers and stack on all the cpus at the time of dumping.
This has been found to be crucial to debug problems where some of the cpus
on an SMP are hung (executing a tight loop, interrupts disabled).
We have this working in the kernel side. We have also added a command to display
the saved registers in the lcrash. We need to add some bits to lcrash
so that it can look at the right (saved) stack when back tracing.
Comments?
