My IBM RS/6000 B50 locks up with 2.6.11rc1, it dies in atkbd_init():

Any idea how to fix it? There is no keyboard or mouse detected. I think
it works ok on ppc64, Anton did not complain yet.

Hi,
It looks like it is hanging in checking AUX, while writing data into
controller. It is simple outb but it is stuck... Could you please
reboot with i8042.debug boot option and resend the log. Also, you may
try booting with i8042.noaux to check if keyboard alone works.

It fails also on PReP, not only on CHRP. 2.6.10 looks like this:
Calling initcall 0xc03bc430: atkbd_init+0x0/0x2c()
atkbd.c: keyboard reset failed on isa0060/serio1
atkbd.c: keyboard reset failed on isa0060/serio0
I'm able to break into xmon, cpu is in cpu_idle, maybe its spinning
somewhere.

So it could not reset it even before, but it was not getting stuch
tough... What about passing atkbd.reset=0?

I will try that.
Adding a printk after the outb() fixes it as well.
Do you have a version of that i8042 delay patch for 2.6.11-rc2-bk6?
Maybe it will help.

Fixes as in "it reports that reset fails" again or it resets the
keyboard cleanly and works fine?

No I don't, and I don't think you need all of it. What happens if you
edit drivers/input/serio/i8042.c manually and stick udelay(7); in
front of calls to i8042_write_data() in i8042_kbd_write() and
i8042_aux_write()?

It doesnt hang if I add printk around the outb.

Doesnt help either, adding printk fixes it.

So this trace is without printk but with udelay, right? This time
keyboard does not hang but NAKs everything instead... What if you aso
add udelay(20) after calls to i8042_write_data()?

Do you know where exactly? Is it some IO port access again?

Its with 2 printk in i8042_write_data(), just adding a printk after outb
in i8042_write_data fixes the hang.

Havent debugged that one, yet. Hopefully a different issue. According to
the logs from 2.6.5, the next message would be
NET: Registered protocol family 2
IP: routing cache hash table of 2048 buckets, 16Kbytes
TCP established hash table entries: 16384 (order: 5, 131072 bytes)

NET: Registered protocol family 1

Probably stupid question - does this box have AT keyboard? Or NAKs are
perfectly valid?

There is nothing connected. 2.6.10-bk11 works, -bk12 not. Thats a
starting point, will look at the differences now.

If I remove this patch from 2.6.10-bk12, it works again.
No drivers were changed, I see lots of "mm" which is scary.
Any takers?

.config contains just enough to get to the atkbd_init() function.
