Description of Problem: The system is a dual processor PIII and I have had the problem with an Ensoniq sound card (ES1370 drive) and the SB Live sound card (emu10k1 driver). Using various sound applications such as realplay, xmms, and mplayer, sometimes the system will hang in a hard freeze (and sound loop) -- requires a hardware reset or power cycle. In addition, I also cannot ssh into the system from another system. Furthermore, I have this system on a Belkin KVM box and when it hangs, I cannot use the keyboard or the Belkin switch to change to another system ... hardware reset is the only way to get out. When the system hangs, the sound "loops" with a usually short segment which will repeat until the hardware reset. As far as showing the problem, I have found that using xmms to play various ogg files rip'ed from cds will demonstrate the problem. Note that there is nothing in any of the logs to show the problem. I suspect that the kernel is going into some kind of loop with everything disabled. Note that I do not see the problem if I reboot and run the non-smp kernel. Version-Release number of selected component (if applicable): 8.0, kernel-smp-2.4.18-14 How Reproducible: yes but not predictable. Somtimes it will run for hours before a freeze and others only a couple of minutes. Processor activity can be light or heavy. Steps to Reproduce: 1. boot smp kernel 2. run some applications which will play lots of music. 3. Additional Information: I do not know if just playing cd's will cause the problem but I doubt it. There is really no way around this other than "don't do that" which just will not work for me.
The motherboard is a ABit VP6 with no on-board sound card ... the SB Live is a pci card. Other info attached.

Oh, not good, not good. I put a fresh install of 7,3 on this system and applied all errata including kernel-smp-2.4.18-10. The problem occurs! This looks bad!
OK, I am going to leave this open for a while but I believe the problem is the POS HPT370 controller that I am using. Because the new DVD-RW drive I installed would not blank cdrw's, I installed a fifth ide device on the builtin HPT370 controller. While I was getting some error message in /var/log/messages about the device, it did seem to operate properly. However, when I ran nmi_watchdog=1 and got the OOPS, it seemed to point to this controllers driver. Therefore, I have pulled the device and will continue testing to see the freeze occurs again. If it does not appear in a week, I will close this report.
no re-occurance ... closing
