please try adding "nmi_watchdog=1" as well Unfortunately I have no luck enabling NMI watched. Got message that local APIC is enabled but no message about testing NMI and NMI interrupt count was 0. (tried 2.4.9-31 & 2.4.18-3 from RedHat and also "myself" 2.4.18). Here is a sample dmesg: Linux version 2.4.18-3 (bhcompile.redhat.com) (gcc version 2.96 20000731 (Red Hat Linux 7.3 2.96-110)) #1 Thu Apr 18 07:32:41 EDT 2002 BIOS-provided physical RAM map: BIOS-e820: 0000000000000000 - 000000000009fc00 (usable) BIOS-e820: 000000000009fc00 - 00000000000a0000 (reserved) BIOS-e820: 00000000000f0000 - 0000000000100000 (reserved) BIOS-e820: 0000000000100000 - 000000000fff0000 (usable) BIOS-e820: 000000000fff0000 - 000000000fff3000 (ACPI NVS) BIOS-e820: 000000000fff3000 - 0000000010000000 (ACPI data) BIOS-e820: 00000000ffff0000 - 0000000100000000 (reserved) On node 0 totalpages: 65520 zone(0): 4096 pages. zone(1): 61424 pages. zone(2): 0 pages.

At least I tried to recompile readprofile with debug info -g. Please see further attachments. Created attachment 61925 [details]
gdb session of crashed readprofile (with debug info)
Created attachment 61926 [details]
map file of my 2.4.18 kernel, that causes readprofile crash.
Created attachment 61928 [details]
patch to catch corrupted map file
Added patch, that catches buffer overrun in while loop. But not yet sure what is the real problem. Maybe - readprofile does not deal with functions in modules (they seem to not be in /boot/System.map - possible cause of readprofile crash?) Also - empty output for 2.4.18-3 kernel is still mysterious. Thanks for the bug report. However, Red Hat no longer maintains this version of the product. Please upgrade to the latest version and open a new bug if the problem persists. The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, and if you believe this bug is interesting to them, please report the problem in the bug tracker at: http://bugzilla.fedora.us/ |
