You can start by either filing a bug in the kernel bugzilla or
alternatively send me full dmesg of the error. Also include output of
/proc/interrupts before and after suspend.

You can also try the following patch:

https://git.kernel.org/cgit/linux/kernel/git/tip/tip.git/commit/?h=x86/urgent&id=db91aa793ff984ac048e199ea1c54202543952fe

It fixes a memory corruption during suspend/resume which might be
related to the issue you are seeing.
