testsuite fails #3

Closed wompydomp closed 11 years ago

wompydomp commented 11 years ago

Hi,

Since I am not quite sure if this is the right place to ask, I hope you're able to help me. I really appreciate that you opened the github-repo (following the discussion on the mailinglist).

I compiled my own kernel ( with a lot of fails, still not sure if everything is the way it's supposed to be) but I ran into the follwing problem when I try to run the latency test from the testsuite. Attached you'll find the dmesg output. Thank you so much for the efford on this project!

Regards, Jo

ShabbyX commented 11 years ago

What is your distribution? Which version of RTAI are you running? Is it the master branch of this repository? The master branch is work in progress, so it's not really stable. You could try the vulcano branch, which reflects the latest official stable release, or the magma branch which reflects the latest official development branch (I suggest vulcano).

NTULINUX commented 11 years ago

Any word on if it works with magma or vulcano? If no response in a week, I'll just close the issue.

Seems like CONFIG_RTAI_MBX wasn't set or something. Kernel 2.6.38.8 was the kernel release, meaning not related to master, perhaps vulcano branch. If so, it should be reported to rtai@rtai.org since it is not showroom related, rather RTAI testsuite. Vulcano branch is simply a clone of the vulcano branch of the official RTAI cvs repo.

Closing issue as it might be an official RTAI bug. ShabbyX, if this issue has not yet been reported to rtai@rtai.org, please do so as this might actually be a valid bug.
