Description of problem:
Kudzu (kudzu-1.1.20-1.1) works just fine with kernel-2.4.22-20.1.2024.2.1.nptl
but locks the machine hard during boot up with
kernel-2.4.22-20.1.2024.2.36.nptl.  No messages, even in text mode.  Just a
freeze up.  

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Update to latest kernel
2. Boot with kudzu service enabled.


Actual Results:  Hard lock (keyboard lights don't respond to keyboard)

Expected Results:  Normal boot.

Comment 2 Steve Bergman 2003-09-05 10:31:28 EDT
More info:

Booting into single user mode and running:

# strace -f kudzu

shows the last system call to be:

open("/dev/psaux", O_RDWR|O_NONBLOCK

(No trailing parenthesis.  No return value.

Running kudzu with the earlier kernel results in a delay of a few seconds at
that point, but then kudzu continues on.

With the current kernel it never recovers.
Comment 3 Steve Bergman 2003-09-05 11:09:20 EDT
Hmm, I guess I should add that I do *not* have a ps2 mouse.  It is USB.
Comment 4 Kaj J. Niemi 2003-09-08 09:16:04 EDT
Yup, I get the same thing here although my hardware is different (attached
hwconf and lspci -vv)

I've got a load of these and this is reproducible on all of them. :)

What does booting with "acpi=off" do in this case?
Comment 8 Kaj J. Niemi 2003-09-08 13:39:01 EDT
I've got APIC and MPS 1.1/1.4 forced _off_ from BIOS. Earlier on the Realtek
cards didn't really work with them enabled at all. I'll see what happens
tomorrow, though, and let you know.
Comment 9 Kaj J. Niemi 2003-09-08 13:39:36 EDT
Oh sorry it was a-c-p-i, not a-p-i-c. ;-) My bad.
Comment 10 Steve Bergman 2003-09-08 14:11:42 EDT
I updated to the latest rawhide today and it now works.

Comment 11 Dave Jones 2003-09-08 14:17:00 EDT
The only thing that could make a difference between 2.4.22-20.1.2024.2.36 and is an update to execshield-B5.
Comment 12 Dave Jones 2003-09-08 14:54:27 EDT
erk, my bad. Theres no kernel update in rawhide yet, so it must have been
something else. Strange.
