Hallo, I'm using xenomai 2.6.4 on kernel 3.8.13 (patch ipipe-core-3.8.13-x86-4.patch)
In attachment you find the kernel config. When I boot the kernel on a recent pc's (Intel(R) Core(TM) i5), I don't get problems, but if I install the same image on an older pc, (Intel(R) Core(TM) Duo CPU T2500 @ 2.00GHz), I get periodic kernel traces after booting without running any real-time process (see below). In the dmesg in attachment, I see a stack trace. (If I build a normal linux kernel without ipipe patch, I get no kernel traces.) Has anyone has a suggestion what could go wrong ? Kind regards, Frederik Message from syslogd@alsipmcp at Nov 6 17:48:01 ... kernel:[ 71.236006] BUG: soft lockup - CPU#0 stuck for 41s!
