Issue is still observed even after blacklisting tg3 driver by giving
"blacklist=tg3 modprobe.blacklist=tg3" in kernel parameter.
Please find the serial logs of the efforts.

Sujith, does the issue happen when "tg3" is blacklisted? Something like
"blacklist=tg3 modprobe.blacklist=tg3" in kernel parameter.

Hi Jeff,
I think we should now go ahead with the SRU request for the fix.
rmmod tg3 does not help workaround the issue.
Fix details:
Revert "PM: ACPI: reboot: Use S5 for reboot"

Issue is still observed even after removing tg3 driver by using "rmmod tg3".
