Title: the machine of lenovo M715 with the AMD GPU (Radeon Vega 8 Mobile, rev ca, 1002:15dd) often hangs randomly Status in HWE Next: Fix Released Status in linux package in Ubuntu: Fix Released Status in linux-oem package in Ubuntu: Fix Released Status in linux source package in Bionic: Fix Released Status in linux-oem source package in Bionic: Fix Released 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.
