https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D267691 --- Comment #1 from hannula@gmail.com --- Looks like I hit a bug that jhb tried to fix in 2012: https://lists.freebsd.org/pipermail/freebsd-current/2012-February/031879.ht= ml But what is strange is that FreeBSD 12 works perfectly on the system, no "hw.mca.enabled=3D0" needed. Furthermore when setting hw.mca.enabled=3D0 the boot now continues further = but crashes with: ahc_isa_identify 14: ioport 0xec00 alloc failed pnp_identify: Trying Read_Port at 203=20 pnp_identify: Trying Read_Port at 243=20 pnp_identify: Trying Read_Port at 283=20 pnp_identify: Trying Read_Port at 2c3=20 pnp_identify: Trying Read_Port at 303=20 pnp_identify: Trying Read_Port at 343=20 pnp_identify: Trying Read_Port at 383=20 pnp_identify: Trying Read_Port at 3c3=20 PHIP Identify complete pnpbios: 13 devices, largest 98 bytes panic: isa_set_pnpbios_handle failed for (null) on bus isa0, error =3D 2 cpuid =3D 0 time =3D 1 KDB: stack backtrace: db_trace_self_wrapper(0,1d906a0,0,b8dde80,2,...) at db_trace_self_wrapper+0x28/f=20 rame 0x22f9c10 vpanic(155e5ec,22f9c4c,22f9c4c,22f9cc4,13ec318,...) at vpanic+0xf4/frame 0x22f9c=20 2c panic(155e5ec,147a78d,8,b8e0870,2,...) at panic+0x14/frame 0x22f9c40=20 pnpbios_identify(1b1b9fc,b8de680) at pnpbios_identify+0x648/frame 0x22f9cc4= =20 bus_generic_probe(b8de680) at bus_generic_probe+0x25/frame 0x22f9ce0=20 isa_probe_children(b8de680) at isa_probe_children+0x12/frame 0x22f9d08=20 configure(8) at configure+0x17/frame 0x22f9d14 mi_startup() at mi_startup+0x214/frame 0x22f9d38=20 btext() at btext+0x5f KDB: enter: panic [ thread pid 0 tid 100000 ] Stopped at kdb_enter+0x34: movl $8,kdb_why db> Why I am reporting this - FreeBSD 13 switched i386 to 686/P6 meaning Pentium Pro should be the minimum supported system. I have no real world use case f= or the machine. --=20 You are receiving this mail because: You are the assignee for the bug.=
