From Bugzilla Helper: User-Agent: Mozilla/4.78 [ja] (WinNT; U) Description of problem: Our IA64 machine has PS/2 Keyboad and mouse, but they never be available RHAS3.0 beta installing. USB keyboard and mouse are enabled with same test. Version-Release number of selected component (if applicable): kernel-2.4.21-1.1931.2.349.2.2.ent How reproducible: Always Steps to Reproduce: 1. Prepare the machine which has PS/2 keyboard and mouse 2. Install RHAS3.0 beta 3. Actual Results: PS/2 Keyboard and mouse are never enabled. If we have USB keyboard and PS/2 mouse, only mouse can't be available Expected Results: Both PS/2 keyboard and mouse are available. Additional info: We guess this is kernel issue, or ACPI BIOS one. A simple patch below: --- linux-2.4/arch/ia64/kernel/acpi.c.org 2003-08-08 11:50:01.000000000 +0900 +++ linux-2.4/arch/ia64/kernel/acpi.c 2003-08-08 19:13:33.000000000 +0900 @@ -578,8 +578,14 @@ fadt = (struct fadt_descriptor_rev2 *) fadt_header; - if (!(fadt->iapc_boot_arch & BAF_8042_KEYBOARD_CONTROLLER)) - acpi_kbd_controller_present = 0; + if (!(fadt->iapc_boot_arch & BAF_8042_KEYBOARD_CONTROLLER) && \ + !(fadt->iapc_boot_arch & BAF_LEGACY_DEVICES)) { + printk( "acpi_kbd_controller_present = 0(%x)\n", + fadt->iapc_boot_arch ); + /* acpi_kbd_controller_present = 0; */ + /* never set acpi_kbd_controller_present as 0, enabling PS/2 KBD */ + fadt->iapc_boot_arch |= BAF_LEGACY_DEVICES; + } sci_irq = fadt->sci_int; Actually our machine has 0 on fadt->iapc_boot_arch. Is this kernel issue? or ACPI?
We've decided to fix our SAL, to set the bit BAF_8042_KEYBOARD_CONTROLLER of fadt->iapc_boot_arch. So it'll never happen. This issue may be closed. Although ACPI spec doesn't seem that current linux is correct. # Windows works fine on same machine, without setting the bit.
Closing, per resommendation of problem submitter.
