Ok, this is fortunately a simple issue: CONFIG_M586=3Dy # CONFIG_M586TSC is not set This forces Xenomai into TSC emulation mode using the PIT. Suboptimal setup, choose at least M586TSC or even something closer to your real processor. The actual problem is the conflict with this option: CONFIG_INPUT_PCSPKR=3Dy That driver also uses the PIT and finally causes the lock-up. Upcoming Xenomai 2.3 detects the conflict and warns you, but 2.2 lets you trap into this without any hint. =2E.. > By the way, when I compiled the rt-system on this second notebook, I go= t > the "Cannot determine dependencies of module ..." not for reiserfs, bu= t > for processor, thermal, jbd, ext3 (in this order and immediately > afterwards a second time, again in this order). As I have already said,= > I could provide you with the messages during build process. Yeah, I know those (likely) SuSE-related warnings as well. I never felt like looking for their reason, I can just say that they are harmless.
