Hi all,
I'm preparing a Toshiba Satellite S1400-153E laptop for field work.
It used to run redhat 9 + RTLinux, but now it runs Ubuntu 6.06 +
Xenomai 2.3.
Unfortunately the latency test shows high latencies (200..500us) at
irregular intervals (5..20 sec) whereas the typical max latency is
around 10 us. It doesn't seem to be related to any user action.
I don't think this thing has SMI, anyway xenomai doesn't detect it.
It also doesn't have a local APIC. What could be the cause of these
high latencies?
Anyone using a laptop of this kind?
Regards,
Theo
