I get the following crash on Cobalt when CONFIG_SERIO=y is set. I realize that this option is not really necessary on Cobalt but the kernel should neverless not crash if it is enabled.

Activating ISA DMA hang workarounds.

I get the following crash on Cobalt when CONFIG_SERIO=y is set. I realize that this option is not really necessary on Cobalt but the kernel should neverless not crash if it is enabled.
Activating ISA DMA hang workarounds.
rtc: Digital UNIX epoch (1952) detected
Real Time Clock Driver v1.12a
Cobalt LCD Driver v2.10
i8042.c: i8042 controller self test timeout.
Unhandled kernel unaligned access[#1]:

The i8042 error message is a little surprising. The Cobalt boards afair have some sort of SuperIO chip on the board which includes PS/2 keyboard even though that has not been wired. I wonder if anybody can take a look at the board what type of SuperIO is there?

Anyway, the kernel code seems to be correct at a glance so I have to assume the PS/2 hardware really doesn't work and I propose below patch.

The i8042 error message is a little surprising. The Cobalt boards afair have some sort of SuperIO chip on the board which includes PS/2 keyboard even though that has not been wired. I wonder if anybody can take a look at the board what type of SuperIO is there?

Maybe Peter Horton can take a look.

Quoted 2 lines

Anyway, the kernel code seems to be correct at a glance so I have to assume the PS/2 hardware really doesn't work and I propose below patch.

That's fine with me.

I get the following crash on Cobalt when CONFIG_SERIO=y is set. I realize that this option is not really necessary on Cobalt but the kernel should neverless not crash if it is enabled.

No SuperIO, but there is a bog standard VIA PCI-ISA bridge which contains a bog standard PS/2 keyboard controller, which you would have thought should just work ...

That's really interesting. I tried latest git (2.6.16-rc5) to see if this is still there. First of all, 32-bit is fine, both regarding i8042 as well as ALSA with a PCI audio card. With a 64-bit kernel, i8042 appears to be okay now. I get:

Serial: 8250/16550 driver $Revision: 1.90 $ 4 ports, IRQ sharing disabled

and the kernel boots fine.

I then built ALSA support into the kernel to see whether
http://www.linux-mips.org/archives/linux-mips/2006-01/msg00325.html
disappeared too. I got almost the same oops as the one I got before because of i8042.

Peter, does that make any sense to you? I assume your recent PCI fix may be related.

Peter, does that make any sense to you? I assume your recent PCI fix may be related.

Those addresses that begin 9b640000 (including the fault address) look very strange. The low 32-bits look like a valid physical address in the PCI space but the top bits definitely don't look right (unless the kernel's playing tricks with unused address bits; I'll have to check the RM523x data sheet to see if they have any effect). Have any of the MIPs experts commented ?
