hid-dummy.ko Input/output error -- causing huge delays

[Luis R. Rodriguez]

FATAL: Error inserting hid_dummy
(/lib/modules/2.6.29-rc6-wl/kernel/drivers/hid/hid-dummy.ko):
Input/output error

I remember reading a thread where you said this was non-fatal and that
hid-dummy.ko would go away. On my system, every now in a blue moon the
above causes a huge delay during the bootup sequence. I'm talking
about a full 1-2 minute delay. Why is the delay so sporadic?

s/once in a blue moon/often/

as it seems I get this now upon every reboot.

So I suppose the problem goes away, when you change -EIO to 0 in
drivers/hid/hid-dummy.c
?

Well now I see FC10 say its starting udev and it just sits there
waiting for the same period of time so maybe it was that (?). But at
the console the hid-dummy is not the last message I see now, but I
guess I wouldn't because it returns 0 now huh.

Sorry, I'm totally confused now :). What you wouldn't?

Actually I saw similar behavior on one of my boxes. I'll recheck if it 
is still present.

Thanks so far.

Hm?

Let me explain what I am concluding:

Whether or not return -EIO is used for the hid_dummy on my FC10 box I
get huge delay during bootup when starting udev. It sits there and
says:

Starting udev:

If hid-dummy return -EIO then immediately afterwards I see the error
for inserting it with the EIO error explained:

FATAL: Error inserting hid_dummy
(/lib/modules/2.6.29-rc7-wl/kernel/drivers/hid/hid-dummy.ko):
Input/output error

Oh nice. Yeah so the huge delay seems to be unrelated to hid-dummy.
