[rtl] patch 0.6-2.0.33

[Brooke Wallace x13349 <brooke@qualcomm.com>]

Hi,

	I just installed RT-Linux on my computer using the latest 0.6 patch on a
brand new 2.0.33 kernel.  The patch worked fine and I was able to compile
the kernel.  I made a boot floppy with the kernel and rebooted. I did a
ksyms and got 7 rt_ symbols.  So I proceeded to try out some of the
examples.  I was following the documentation very carefully and insmod
rt_prio_sched.o and rt_fifo_new.o still no problems.
Then after compiling an example program, let's say example 2-tasks, I tried
to do an insmod on rtprocess.o and it failed with the following message:

[root@btwallac-home 2tasks]# /sbin/insmod rt_process.o  
rt_task_wait undefined
rt_get_time undefined
rt_task_make_periodic undefined
rt_task_suspend undefined
rt_task_init undefined
rtf_create_handler undefined
rt_task_delete undefined
Failed to load module! The symbols from kernel 2.0.33 don't match 2.0.33
[root@btwallac-home 2tasks]# 


However the first two RT modules loaded just fine:

[root@btwallac-home modules]# /sbin/insmod rt_prio_sched.o 
[root@btwallac-home modules]# /sbin/insmod rt_fifo_new.o   
[root@btwallac-home modules]# /sbin/lsmod 
Module:        #pages:  Used by:
rt_fifo_new        2            0
rt_prio_sched      1            0


And ksyms shows that those missing symbols were there:

[root@btwallac-home 2tasks]# /sbin/ksyms -a | grep ' rt_'
04816004 rt_startup     [rt_prio_sched]
04816418 rt_current     [rt_prio_sched]

0013473c rt_fifo_get_R5be8c660
001345d8 rt_fifo_put_Ra7242823
[root@btwallac-home 2tasks]# 

Can anyone tell me where I went wrong?

Also when I run shutdown a get the following message about a thousand times
which made me concerned:

INIT: error reading initrequest


Here is a verbose insmod message when trying to load one of the testing
examples:

Thanks a lot for any help in advanced.
