Hello,
I'm trying to set up RELENG_5 on a box, and got some panices.
1) Box configuration: MSI MS-6568 (SiS740 + SiS961B), Duron 1100, Realtek
RTL8101 on-board, BIOS v1.2 (04102002, the latest)
2) Panices are reproducible during all last RELENG_5 stages (3,4,5 betas)
3) Kernel config is derived from GENERIC by commenting out unneeded devices
and adding some options:
=== cut here ===
machine i386
cpu I686_CPU
ident Pine
makeoptions DEBUG=-g # Build kernel with gdb(1) debug symbols
[...]
options KDB # Enable kernel debugger support.
options DDB # Support DDB.
options GDB # Support remote GDB.
options INVARIANTS # Enable calls of extra sanity checking
options INVARIANT_SUPPORT # Extra sanity checks of internal structures, required by INVARIANTS
options WITNESS # Enable checks to detect deadlocks and cycles
options WITNESS_SKIPSPIN # Don't run witness on spinlocks for speed
options BREAK_TO_DEBUGGER
options KDB_TRACE
options AUTO_EOI_1
options INCLUDE_CONFIG_FILE
options QUOTA
options IPFIREWALL
options IPFIREWALL_FORWARD
options IPFIREWALL_DEFAULT_TO_ACCEPT #allow everything by default
options IPDIVERT #divert sockets
options BRIDGE
options DUMMYNET
options SMP # Symmetric MultiProcessor Kernel
device apic # I/O APIC
[...]
=== cut here ===
Panices.
--------
1) When MPS 1.4 is enabled with the BIOS setting and ACPI disabled either by
BIOS or by unsetting `acpi_load' loader variable, the kernel panices
immediately with "panic: Multiple entries for PCI IRQ 16" message. As one
can see from #1 Bootlog, there are really two entries for IRQ16. I think
this is the BIOS bug, but I also think the diagnostics for this situation
should be more precise than that.
2) Disabling MPS or enabling ACPI allows the system to boot and to run some
time, but (depending on the system load) the system panices with "panic:
_sx_xlock (user map): xlock already held @ /.../sys/vm/vm_map.c:2997".
I could dig some additional info from this situation if I be told what to
do.
Logs.
