Linux system is consistently getting unresponsive with below serial console output. The similar serial console output is observed every time the issue is occurred.
Steps to reproduce this issue are unknown as of now. But, this issue is not observed when all parameters related to acpi are disabled from BIOS.
I am newbie to debugging kernel oops. Please let me know what could be the problem and how can I resolve this issue. Any pointer or help will be very important.
Stack trace is as,
