I'm running gentoo-sources-2.6.14-r5 on an IBM 5664 Netfinity server with no problems until I try running Rosegarden. Every time I have the system reboots after 30-60 seconds with the following error message in the kernel log: Uhhuh. NMI received for unknown reason 35 on CPU 0. The one unusual hardware component of the server is an M Audio Delta 1010 that has served me faithfully to date using Ardour. It may have something to do with the MIDI interfaces since this is the first time I'm trying to do anything with MIDI. Note the device initialization phase of dmesg includes: oprofile: using NMI interrupt. I did an strace of rosegarden and it generated several megabytes of data. The messages rosegarden prints don't appear to reveal any glaring problems to my ignorant eyes. I searched the IBM website for non-maskable interrupt issues without success. As I bought the box on eBay I do not have IBM software or documentation, nor can I afford support. I would appreciate the assistance of the more knowledgable among this list with determining the best direction to go with this problem. The full kernel log and dmesg files follow. = = = = = = = = = = = = = = = = = = = = = = = = = = = dlc@muse ~ $ sudo cat /var/log/kernel/current Password: Jan 16 01:12:00 [kernel] [4294667.296000] Linux version 2.6.14-gentoo-r5 (root@muse) (gcc version 3.3.6 (Gentoo 3.3.6, ssp-3.3.6-1.0,pie-8.7.8)) #1 SMP PREEMPT Mon Jan 16 01:00:29 EST 2006 Jan 16 01:12:02 [kernel] [ 40.966297] eth0: link up, 100Mbps, full-duplex, lpa 0x45E1 Jan 16 01:12:30 [kernel] [ 68.762937] mtrr: Serverworks LE rev < 6 detected.

Strange. I don't recall seeing this reported before. The usual cause of action is to test the most recent kernels and then report it as an upstream bug. Can you please confirm that the bug still appears on the latest development kernel (currently 2.6.16-rc1)?

Can you see if any BIOS upgrades are available? It would also be worth booting a kernel without ACPI or APM and seeing if that makes any difference.
They are already disabled. I'll check on the BIOS upgrade question.
No new updates since October 2002, 1.16, which is what I'm running.
I found another way to trigger the NMI 35. Using qjackctl's Connections window to connect the Delta's MIDI to ardour's seq causes a 6.22 second lockout followed by a reboot after 15 more seconds. The kernel NMI message is generated in this instance, also.
Should I report the bug upstream? If so, would that be at kernel.org's bugzilla service or somewhere else?
Yes, I'm out of ideas, please report this at http://bugzilla.kernel.org and post the new URL here.
