The question then becomes: Why doesn't the race condition happen with only one screen? Perhaps it's a matter of speed. With a single display, the driver detect the displays, read/parse the EDID data, initialize in time. But then that doesn't explain why the crash still occurs if you boot with one DisplayPort monitor and attach another after X is running. One thing I've been trying to work out is the difference between vega21_ppt.c and vega20_hwmgr.c is, as they both contain slightly different or identical versions of the same functions. It looks like the functions in vega20_hwmgr.c take precedence but it's strange to see this duplication and both files are worked on in the commit history. Take a look at vega20_set_uclk_to_highest_dpm_level and vega20_apply_clocks_adjust_rules in both for examples.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
