Recently I was running a number of tests against 5.3-STABLE (btw,
RELENG_5 labeling the system as 5.3-STABLE might be very confusing in a
situation where there's not even a 5.3-RELEASE yet, if one doesnt follow
how -STABLE are treated compared to "security branchs"), in a SMP system
with multiple SATA RAID, and it was not responding well, had a number of
freezes under stress tests; Some of those problems could be minimized
running BSD as the scheduller instead of ULE;
Now -RC1 shows the same performance 5.2.1 used to, also w/ SCHED_BSD,
but with ULE it stops responding well sometimes.
This first system is a dual-P4 3.0; but with older SMP systems I get a
problem on 5.3 that does not happens on 5.2.1;
The system is a 4-proc Pentium Pro, it installs fine, but when we start
using more CPU (say, running stress(8) or building a port) it panics w/
Panic: APIC: Previous IPI is stuck
cpuid: 0
boot() called on cpu#0
Uptime: 3h44m23s
Cannot dump. No dump device defined
Automatic reboot in 15 second - press a key ...
cpu_reset called on cpu#0
cpu_reset: stopping other CPUs
Panic: APIC: Previous IPI is stuck
cpuid=0
boot() called on cpu#0
Under 5.2.1 it runs fine.
What kind of more detailed info can I send to help tracking this behaviour?
