Hi,

I am running RTAI 3.1 w/ 2.6.8.1 kernel.  The hardware is an Intel
80486-DX4 75 MHz laptop with 24 MB RAM.  Kernel has been compiled with
Processor Type -> 486.

With kern/preempt:

Adeos: Domain RTAI registered.
RTAI[hal]: 3.1 mounted over Adeos 2.6r7/x86.
RTAI[hal]: compiled with gcc version 3.3.2 (Mandrake Linux 10.0
3.3.2-6mdk).
RTAI[malloc]: loaded (global heap size=131072 bytes).
RTAI[sched_up]: loaded.
RTAI[sched_up]: fpu=yes, timer=periodic.
RTAI[sched_up]: standard tick=1000 hz, CPU=1193180 hz.
RTAI[sched_up]: timer setup=1676 ns, resched latency=2514 ns.
Error opening /dev/rtf/0


CPU USE SUMMARY
# 0 -> 127305
END OF CPU USE SUMMARY

RTAI[malloc]: unloaded.
RTAI[sched_up]: unloaded.
Adeos: Domain RTAI unregistered.
RTAI[hal]: unmounted.

The program was unable to open /dev/rtf/0.  This could be because I am
compiling on a different machine and then running on a different one.
Which devices to create manually in /dev?  Anyone know?


With kern/latency:

Adeos: Domain RTAI registered.
RTAI[hal]: 3.1 mounted over Adeos 2.6r7/x86.
RTAI[hal]: compiled with gcc version 3.3.2 (Mandrake Linux 10.0
3.3.2-6mdk).
RTAI[malloc]: loaded (global heap size=131072 bytes).
RTAI[sched_up]: loaded.
RTAI[sched_up]: fpu=yes, timer=periodic.
RTAI[sched_up]: standard tick=1000 hz, CPU=1193180 hz.
RTAI[sched_up]: timer setup=1676 ns, resched latency=2514 ns.

[system freezes for a while]

Then I get a scrolling list of what looks like call traces...
[xxxxxxx] rcu_process_callbacks+0x0/0x130
[xxxxxxx] do_posix_clock_monotonic_settime+0x0/0x10
[xxxxxxx] do_posix_clock_monotonic_gettime+0x0/0x50
[xxxxxxx] __adeos_ack_common_irq+0x0/0x70
[xxxxxxx] irq_entries_start+0x0/0xe00

(The above two entries repeat about 218 times with
irq_entries_start+0x10..0x20..0x30..0x40.........0xda0)

[xxxxxxx] adeos_sync_console+0x0/0x60
[xxxxxxx] rtai_ssrq_trampoline+0x0/0x150  [rtai_hal]
[xxxxxxx] __adeos_set_root_ptd+0x0/0x20
[xxxxxxx] __adeos_get_root_ptd+0x0/0x20

All this is scrolling at full speed on the screen so I could be not 100%
correct.  It's a good thing my full speed is only 75 Mhz allowing me to
read it somewhat at least.

Does anyone have any clues??

Regards,

Umar
