From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; ja-JP; rv:1.6) Gecko/20040528 Debian/1.6-7 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): kernel-2.4.21-17.EL How reproducible: Always Steps to Reproduce: 1. Boot up OS 2. Issue INIT interrupt 3. Actual Results: Nothing displayed on console Expected Results: The message "Entered OS INIT handler." appears on console, then register information and some other information will follow. Additional info: 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. *** This bug has been marked as a duplicate of 130800 ***
