Hello, I have rebuild my Kernel 2.6.37.6-x86 and uses xenomai-head.git. ( is this xenomai-2.6 git ? ) This version has the same problems on the Core 2 Duo E8400 machines.
But there are some strange kernel messages on startup: May 18 16:07:33 (none) user.warn kernel: CE: hpet3 increased min_delta_ns to 7500 nsec May 18 16:07:33 (none) user.warn kernel: CE: hpet3 increased min_delta_ns to 11250 nsec May 18 16:07:33 (none) user.warn kernel: hrtimer: interrupt took 5978 ns ... May 18 16:07:33 (none) user.warn kernel: CE: hpet2 increased min_delta_ns to 11250 nsec ... after a start of latency ( via ssh ) the linux domain will slow down and the sata driver will come in trouble. If I rebuild my Kernel with CONFIG_HPET_TIMER disabled, latency will run normally on the Core 2 Duo E8400 machines. CONFIG_HPET_TIMER has to be disabled on faster Core 2 Duo machines! There must be a consistency problem! ( probably in io_apic- handling with CONFIG_HPET_TIMER enabled ) I will rebuild and test my kernel with stable 2.5.X xenomai versions and ADEOS patches with CONFIG_HPET_TIMER disabled! Thanks in advance!

So, I am going to try again: could you try and get the console output on serial console or netconsole? If you can not, could you try booting in text mode, and see if you have some traces when the system has issues? Could you try disabling CONFIG_PCI_MSI in your kernel configuration? -- Gilles. _______________________________________________ Xenomai-help mailing list [email protected] https://mail.gna.org/listinfo/xenomai-help
