ruslan Posted July 21, 2020 Share Posted July 21, 2020 I prepared Catalina 10.15.6 installation flash drive according to this manual: When I try to boot from it, before I see installer window I get the panic: In Memory Panic Stackshot Succeeded ** Bytes Traced 279168 ** I tried both attached clover versions (r5058 and r5118) with both configs from e6230 catalina clover pack #2 (with and without xcpm). Bios version is A20, bios config is as described in the post above. Link to comment Share on other sites More sharing options...
ruslan Posted July 24, 2020 Author Share Posted July 24, 2020 Update: it works with Clover r5120 and config_xcpm_(up_to_10.15.3).plist. ACPI/patched folder must be empty (if I copy files from E6230_Catalina_Clover_Pack_#2/ACPI/patched to Clover, I get kernel panic before graphic mode started, error message described in first post).

Administrators Hervé Posted July 24, 2020 Administrators Share Posted July 24, 2020 Don't use r5120, stick to r5119. Latest Clover release appears buggy on the CPU power management side. You may find that, all of a sudden, it won't boot/reboot. 1 Link to comment Share on other sites More sharing options...
ruslan Posted July 24, 2020 Author Share Posted July 24, 2020 Thank you, Herve! I downgraded clover to r5119. Now everything seems to be okay except external display (it's native resolution is 2560x1440), that is connected to DisplayPort on PR02X docking station: it is blinking unevenly. I think of somehow tweaking frame buffer size. Am I heading in the right direction? Also, I managed to use another config.plist (from E6230_Catalina_Clover_Pack_#2): I generated ssdt.aml and ssdt.dsl with ssdtPRGen.sh script, copied them to ACPI/patched as well as DSDT.aml and DSDT.dsl (from E6230_Catalina_Clover_Pack_#2 since I'm not sure how to generate them). With these files system is also stable, issue with external display still present. Link to comment Share on other sites More sharing options...
