Yet another problem running latencytest

Yet another problem running latencytest

[Ivica Ico Bukvic]

Hi all,

I've recompiled my 2.6.5 kernel with rtc compiled in and was able to install
latency-test module. However, now when I run the run_tests the program goes
through initial 2 "draw 500x500 square" tests and then every following test
simply does something like this:

starting diskread (or whatever else is being tested) test..............
error opening device

I've properly edited the latencytest.config file to reflect the proper
directories and I can see that the tmpfile1 and tmpfile2 are being generated
during the tests (and the disk is working) but at the end of the test all
the logfiles are empty and there are no png files in the test directory.

I do not have a /dev/midi0 in my /dev folder (I think mdk 10.0 community I
am using uses devfs), but even if I created a sym-link to /dev/midi00 which
does exist, it still failed.

Any ideas?

/dev/midi0 is NOT identical with /dev/midi00.
the former is a device for tclMIDI while the latter for general (real)
MIDI devices.  i chose /dev/midi0 because tclMIDI is almost dead, so
it unlikely conflicts.

try to create /dev/midi0 via

	# mknod /dev/midi0 c 35 0
