Re: port-i386/41267: 5.0 RC4 does not detect second CPU in VIA VT-310DP motherboard

Hello,

Unfortunately I didn't get any response to my last message so I
debugged the system a little bit more... There is some small
information that I missed previous times and can be helpful. I booted
the system with debug messages (-vx) and got a bit more information.
Firstly I received x86_ipi_init: ESR 00000040 message (it is from
lapic.c x86_ipi_init function and target value equals 1). It means
that IPI with illegal vector was received by Intel APIC specification.
Maybe this is the point where the problem began? It happens before
cpu_start_secondary and subsequently tsc_read_bp is executed (where
I'm getting infinitive loop). Secondly, I also compared various values
between correctly working system (dual core Athlon II X2) and VT-310DP
in tsc_read_bp function during execution. It seems that these values
were set correctly except that tsc_sync_cpu never becomes null on
VT-310DP. I used quite recent NetBSD-current for tests so the problem
remains in current version. Here is updated boot log with debug
messages:
