[1.] One line summary of the problem:

An oops in kmem_cache_alloc during high IO.

[2.] Full description of the problem/report:

Seemingly any high I/O for more than a minute or two will produce an oops in kmem_cache_alloc. I first came across this while resampling an audio book using the program "resample" from the following sh loop:

	for dir in 1 2 3 4 5 6; do
		cd $dir
		for file in *; do
			resample -to 16000 $file ../16k/$dir/$file
		done
	done

Somewhere around 600-900 MB of resampled WAV files, I get an OOPS which I wasn't able to capture. I can reproduce it easily. I wasn't able to get any OOPS-dumping tools to work (due to my own lack of understanding, I'm sure) and the system panics saying "In interrupt handler -- not syncing". This data was being both read from and written to the same ext3 partition (journaling enabled, if it matters).

I tried reproducing the problem on another partition with this sh script:

	while 1; do
		resample -to 2000 /tmp/junk.wav /tmp/junk2.wav
		rm junk2.wav
	done

This produced another OOPS that caused the system to panic. I did this twice. The second time I noticed at the bottom the panic message said:

	<6>APIC error on CPU0: 00(80)

I didn't notice that the first time because I rebooted too quickly. Now that I knew it would happen regardless of the partition, I tried to test whether the input or output, or both, is the problem. The following test of the output caused an OOPS.

	while 1; do
		dd if=/dev/urandom of=/tmp/junk bs=1024 count=40960
		rm /tmp/junk
	done

Actually, that produced two OOPSs in kmem_cache_alloc without making the system panic. The output of ksymoops is below. The system didn't panic, but various commands would get stuck in D-state. e.g. "vim /var/log/messages" did get stuck but "tail -n 100 /var/log/messages /root/oops.txt" did not.

[3.] Keywords (i.e., modules, networking, kernel):

No modules loaded.

[4.] Kernel version (from /proc/version):

Linux version 2.6.7-5 (root@lukahn) (gcc version 3.3.4 (Debian 1:3.3.4-6)) #1 Mon Aug 2 18:49:03 CDT 2004

[5.] Output of Oops.. message (if applicable) with symbolic information
resolved (see Documentation/oops-tracing.txt)

Below is the output of ksymoops for the oops data gathered from /var/log/messages after the last two oops described above.

ksymoops 2.4.9 on i686 2.6.7-5. Options used -V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.6.7-5/ (default)
-m /boot/System.map-2.6.7-5 (default)

Warning: You did not tell me where to find symbol information. I will assume that the log matches the kernel and modules that are running right now and I'll use the default options above for symbol resolution. If the current kernel and/or modules do not match the log, you can get more accurate output by telling me the kernel version and where to find map, modules, ksyms etc. ksymoops -h explains the options.
