Bug Description

[Impact]
On the machine of Lenovo M715, there is an AMD GPU (1022:15dd rev ca), when it
switchs to amdgpufb, the system will hang randomlly, sometimes it hangs during
boot, reboot or poweroff, sometimes it hangs with longtime standby.

[Fix]
Through bisecting, I found this patch can fix the problem, looks like without
this patch the ATOM BIOS can't be parsed correctlly.

[Test Case]
Did the test of "boot, reboot and poweroff" 5 times, worked very well.
Let the system standby over one night, worked very well.

[Regression Potential]
Very low, I tested this patch on at least 6 differnt lenovo machines
and those machines have different AMD GPUs on them, all of them worked
as well as before.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-bionic' to 'verification-done-bionic'. If the problem still exists, change the tag 'verification-needed-bionic' to 'verification-failed-bionic'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
