Greetings,
I'm testing on 9.2-STABLE, and was experimenting on an AMD sempron
(140). Booting from the boot-only, or DVD-1 DVD's doesn't emit the
entire dmesg(8) output. Building, and installing a custom kernel also
didn't provide the full dmesg(8) output.
Specifically; it omits the top N lines (N = as yet, undetermined Number).
I have no idea why, or how to correct this. I'm pretty confident
the processor, and motherboard (MSI) are not too new for FreeBSD.
Example (dmesg) output:
pci_link8: Picked IRQ 21 with weight 0
pcib0: slot 2 INTA routed to irq 21 via \134_SB_.LUB0
ohci early: SMM active, request owner change
found-> vendor=0x10de, dev=0x03f2, revid=0xa3
domain=0, bus=0, slot=2, func=1
class=0c-03-20, hdrtype=0x00, mfdev=1
cmdreg=0x0006, statreg=0x00b0, cachelnsz=0 (dwords)
lattimer=0x00 (0 ns), mingnt=0x03 (750 ns), maxlat=0x01 (250 ns)
intpin=b, irq=11
powerspec 2 supports D0 D1 D2 D3 current D0
map[10]: type Memory, range 32, base 0xdff7ec00, size 8, enabled
that's from /var/run/dmesg.boot. /var/log/messages gives me no more than
dmesg(8) does. Interestingly, misc/cpuid returns:
