Subject: [Xenomai-core] Troubles with switchtest
Date: Wed, 13 May 2009 14:49:12 +0200	[thread overview]
Message-ID: <4A0AC1C8.4050006@domain.hid> (raw)

Hi Gilles,

I'm currently facing a nasty effect with switchtest over latest git head
(only tested this so far): running it inside my test VM (ie. with
frequent excessive latencies) I get a stalled Linux timer IRQ quite
quickly. System is otherwise still responsive, Xenomai timers are still
being delivered, other Linux IRQs too. switchtest complained about

    "Warning: Linux is compiled to use FPU in kernel-space."

when it was started. Kernels are 2.6.28.9/ipipe-x86-2.2-07 and
2.6.29.3/ipipe-x86-2.3-01 (LTTng patched in, but unused), both show the
same effect.

Seen this before?
