Immediately afterward the machine reached S=shutdown, M=mountroot, F=disk detect fail, R=reset SSMSSSSMSSSF Next I set device tree only, per your instructions and it reached RSFRFRFR so I tried ACPI only, reaching FR so I put back DT+ACPI, with result SMMRSSMSSSSSSSMFRS at which time I pulled out the FT232 usb-serial link. That reached SSMSSSMSSMMMSSFFSFSSSFSSS Looks to me like pulling the FT232 didn't help, DT+ACPI works better than either alone. 35 shutdown -r 10 mountroot failures 9 disk detection failures That's actually pretty good for the JMS577 enclosure. The world/kernel upgrade to stable/13-5ec288b57: Wed Oct 5 16:55:43 PDT 2022 seems to have been helpful (not sure why), omitting the FT232 didn't help much, if at all. Compared to yesterday I'm tempted to call it progress. One thing I forgot to mention: The microSD formerly hosted a RasPiOS installation. I simply cleaned out the DOS partition and installed the EDK2 files. At one point during buildworld I ran gstat and saw reports of zero activity for the microSD partitions. I didn't think the kernel would even notice them. Is that to be expected? Thanks for reading! bob prohaska
