>Release:        5.3 and 5.4 beta 1
>Organization:
>Environment:
cannot boot install disk (using PC with Celeron D)      
>Description:
Install disks for 5.3 or 5.4 beta 1 will not boot properly on my PC.
I get the sysinstall screen but no ide controller or disks are found.
ata0-slave: failure - ATA_IDENTIFY timed out
ata0-master: same thing
Two disks in my pc, boot cannot find IDE controller
WORKS FINE on FreeBSD 4.9, 4.10, and 4.11 !
Using a Linux distro, I get the following from dmesg:
VP_IDE: IDE controller at PCI slot 0000:00:11.1
ACPI: No IRQ known for interrupt pin A of device 0000:00:11.1 - using IRQ 255
VP_IDE: chipset revision 6
VP_IDE: not 100% native mode: will probe irqs later
VP_IDE: VIA vt8235 (rev 00) IDE UDMA133 controller on pci0000:00:11.1
  ide0: BM-DMA at 0xfc00-0xfc07, BIOS settings: hda:DMA hdb:DMA
  ide1: BM-DMA at 0xfc08-0xfc0f, BIOS settings: hdc:DMA hdd:pio
hda: ST380011a, ATA DISK drive
hdb: ST380011a, ATA DISK drive
--- by the way, we are trying to boot freebsd on hdb
--- so we will leave out some stuff about other hd, etc.
Using cfq io scheduler
ide0 at 0x1f0-0x1f7, 0x3f6 on irq 14
hdb: max request size: 1024KiB
hdb: 156301488 sectors (80026MB) w/2048KiB Cache, CHS=9729/255/63, UDMA(100)

Also, a Linux pci probe yields:
00:11.1 IDE interface : VIA Technologies, Inc. VT82C586A/B/VT82C686/A/B/VT823x/A/C PIPC Bus Master IDE (rev 06)
>How-To-Repeat:
Happens every time I try to boot 5.3 or 5.4 beta 1.
>Fix:
      None.
