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. -- To unsubscribe from this list: send the line "unsubscribe linux-gpio" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
