I am attempting to upgrade to Xeno 2.6.2.1 / Ipipe 3.2.21 from
a working Xeno 2.5.6 / Ipipe 2.6.30.3 configuration
I am getting a Kernel Panic not syncing kernel stack overflow errors
with the new kernel.
The application is a kernel module that operates soley from interrupts
and communicates to user space with applications with shared memory. It
has been running with the earlier kernels without issues for many years.
Below are the messages I get when the system crashes.
If anyone has any hints based upon the data when it crashes below it
would be greatly appreciated.
