Hello,
I'm currently setting up a PC for Xenomai-Tests. I'm using my good old
PC with an Athlon XP (Thunderbird) for this purpose. The kernel hangs at
boot time when I enable APIC via boot argument (lapic). With local APIC
disabled the kernel boots but I see some Opps messages while running the
latency test and trying a slogin to the system (in the scheduler). Are
there any known issues with this X86 arch? I remember, that I have seen
similar problems with my (old) PIII-Notebook (lapic did not work).
No known issues, both scenarios *must* work, the P-III at least in PIC
mode when Linux refuses to enabled lapic on boot.
Some athlons have a buggy local APIC, so disabling it may be the best
option.
Ah, I found some similar statement on the RTAI mailing list as well.
Thanks for the info.
Wolfgang.
