 Hi,
 
 here it is an IBM System x3250. If booting via pxe or from
 the SATA disk attached to an mpt(4) everything is fine.
 
 Booting from a CF connected via a CF-to-PATA adaptor (the
 CDROM was disconneted) I get the following stack trace
 continously scrolling on vidconsonle. No matter what I tried
 I could not get it on comconsole where everything else appeared.
 So this is hand transcribed from a camera picture.

 BTX halted
 
 
 Thinking that it only seems to happen on the PATA ports, there is also
 another PR: i386/72960: BTX halted with Promise Tx2000 Raid
 
 The IBM server here says:
 atapci0 at pci0:0:31:1:    class=0x01018a card=0x03461014 chip=0x27df8086 rev=0x01 hdr=0x00
      class      = mass storage
      subclass   = ATA
 
 atapci0: <Intel ICH7 UDMA100 controller> port 0x1f0-0x1f7,0x3f6,0x170-0x177,0x376,0x30a0-0x30af at device 31.1 on pci0
 ata0: <ATA channel 0> on atapci0
 ata0: [ITHREAD]
 ata1: <ATA channel 1> on atapci0
 ata1: [ITHREAD]
 
 And that's the CF card:
 ad0: 976MB <TOSHIBA THNCF1G02QG 3.00> at ata0-master PIO4
 
 (obviously I got this info after booting from mpt/disk)

 Software is harder than hardware  so better get it right the first time.
