Description of problem:
IPF OS_INIT handler (which is implemented in arch/ia64/kernel/mca.c)
is called when INIT interrupt is issued.
The handler in RHEL3 prints the processor's register information
to the console.
It works on 2.4.21-15.EL, but it does not work on 2.4.21-17.EL.
I also tried 2.6.7 and it works.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Boot up OS
2. Issue INIT interrupt
Actual Results: Nothing displayed on console
Expected Results: The message "Entered OS INIT handler." appears on
then register information and some other information will follow.
I tried 'dmesg -n 8' to display all messages to console,
but it doesn't work either.
With 2.4.21-15.EL kernel, the expected messages appear on console.
Do you still see this bug in the latest RHEL3 update kernel?
I don't have an access to the machine currently
and cannot answer promptly. I'll check if I can
find a way to test.
Is it just a confirmation?
Or are there any related fix in the recent kernel
which might affect this bug?
If so, should I try any specific version?
I just started to look at this bug and will be helpful if you can see if the
problem still exist on the latest RHEL3 U8 kernel.
OK, thanks for looking.
I tried 2.4.21-42.EL on currently available machine
and saw no problem.
Please close this bug.
This problem was fixed in RHEL3 U4.
