There is an extra space between isa and `isa_attach; this must be removed... > it tried booting with > "-kdvs -B acpi-user-options=2,acpi-enum=off,acpi_enum_debug=0xffff" > and setting moddebug to 80000000 in the debugger and > I still end up in the same place > > ... > installing isa, module id is 37. > installing busra, module id is 38. > isa0 at root > <hang> The "isa0 at root" line should be printed from isa_attach(), line 220. After verifying that it really is hanging inside isa_attach(), the next step would probably be to use the kernel debugger and single step though the isa_attach() / isa_alloc_nodes() code to narrow down where exactly the kernel is hanging... I suspect that the problem is somewhere with one or more of acpi, ps/2 keyboard / mouse, usb keyboard / mouse, usb keyboard legacy emulation, isa serial port... What kind of keyboard are you using? Could you try ps/2 instead of usb keyboard / mouse devices (or vice versa)? Could you try to play with the bios "usb legacy emulation" setup option ? -- This message posted from opensolaris.org
