I second that! Running -current since October and never had a serious SMP
problem.

Hmm, I only had one nasty kernel panic once during installworld, but I
don't think that was hardware related. I must have done at least 50
buildworld's or so since beginning of October; no crashes.

My main system is running dual 450 Mhz. Like I said earlier in the thread,
it's running on a 300 Watt PS with a couple of extra fans to cool the hard
drives, two 7200 RPM disks, 2 network i/f's, scsi, CD reader and writer,
tape unit and zipdrive.  I think the PS is pressed to its limits because if
I add just one more drive (5400 RPM IDE disk) it's over the edge. Those
Celeron's must be eating lot's of power (they are 400 Mhz ones running at
75 Mhz bus speed).

I'm doing it currently. The HPT-366 controller is a completely separate
device. On my bootup, the system doesn't detect any "normal" ide devices
(you can't autotype them in the bios either), then the screen goes blank
and the HPT comes up with its disk detection. Next is the Adaptec detection
and the boot proceeds. In the BIOS you can choose EXT=[ATA,SCSI] and I
have the boot sequence set to EXT,C,A. EXT=ATA.

The ATA driver nicely autodetects (from dmesg):

ata-pci1: <HighPoint HPT366 ATA controller> irq 18 at device 19.0 on pci0
ata-pci1: Busmastering DMA supported
ata2 at 0xb000 irq 11 on ata-pci1
ata-pci2: <HighPoint HPT366 ATA controller> irq 18 at device 19.1 on pci0
ata-pci2: Busmastering DMA supported

ad0: <WDC AC418000D/J78OA30K> ATA-4 disk at ata2 as master
ad0: 17206MB (35239680 sectors), 34960 cyls, 16 heads, 63 S/T, 512 B/S
ad0: 16 secs/int, 32 depth queue, UDMA66

I would like to know how HOT other people's processors get. In the
stationary situation I have a system core (= processor average) temperature
of 46 and a case temperature of 50 degrees Celcius/Centigrade. 

Don't ask why case temperature is higher than core temperature! I don't get
it either. The hard drives are not even above 30 degrees. Maybe it's the
graphics board (viper 550 agp): it's doing 1600x1200@85Hz.  

I once clocked the system at 500 Mhz (83 Mhz bus), which runs fine but
then things get way too hot. 

Regards, 

Dave Boers.
