I had forgotten that the boot attempts now get a FreeBSD panic (seen via serial console use): panic: ram_attach: resource 5 failed to attach cpuid =3D 0 time =3D 1 KDB: stack backtrace: #0 0xffff00000050f450 at kdb_backtrace+0x58 #1 0xffff0000004ba930 at vpanic+0x19c #2 0xffff0000004ba790 at panic+0x44 #3 0xffff00000086e7c0 at ram_attach+0x1ac #4 0xffff0000004fba88 at device_attach+0x3f8 #5 0xffff0000004fdce8 at bus_generic_new_pass+0x120 #6 0xffff0000004fdc78 at bus_generic_new_pass+0xb0 #7 0xffff000000500450 at root_bus_configure+0x40 #8 0xffff00000042b600 at mi_startup+0xdc #9 0xffff0000000008ac at virtdone+0x70 It is a FreeBSD problem, not an EDK2 problem. My old notes on the lists about the FreeBSD problem are at: = https://lists.freebsd.org/archives/freebsd-current/2023-September/004775.h= tml I do not know if v1.34 might sidestep the mishandling in FreeBSD or not. =3D=3D=3D Mark Millard marklmi at yahoo.com
