We have a custom PCIe card that raise a MSI, with a normal (not rtdm) driver. It appears that the interrupt comes just once and then is stuck. It work under plain Linux, but I cannot rule out a HW timing bug either. The wiki pages http://www.xenomai.org/index.php/FAQs http://www.xenomai.org/index.php/Configuring_x86_kernels say not to enable MSI on x86, with a link to a very old (2008) discussion. I found a newer mail https://mail.gna.org/public/xenomai-help/2010-01/msg00095.html claiming that MSI is okay. Is there a known problem with MSI and Xenomai? If so, where/how can I start to get working on fixing it? (I don't need the MSI in a rtdm or adeos context.) Thanks, Richard
