Symptoms:
	PHKL_28130:
	( SR:8606270547 CR:JAGae34783 )
	When attempting to save a crashdump to an ATA disk,
	this error message appears:
	ERROR: can't write dump header to device /dev/dsk/c2t0d0.
	Dump aborted.

	( SR:8606276350 CR:JAGae40428 )
	The DVD and LS240 devices cannot be used on the Intel
	OEM i870 platform.

	( SR:8606271532 CR:JAGae35740 )
	System hangs if a real-time process deadlocks with a
	process waiting for a non-realtime IDE IO to complete.

	( SR:8606270190 CR:JAGae34428 )
	On a busy system, the "ioscan" command will cause the
	message "I/O hardware probe timed out" to appear in the
	kernel message buffer.

Defect Description:
	PHKL_28130:
	( SR:8606270547 CR:JAGae34783 )
	If an IO is active on the same IDE channel as the dump
	device when a TOC or MCA occurs, no new IOs can start on
	that channel.

	Resolution:
	At the start of a crash dump, the IDE dump driver resets
	the IDE interface.

	( SR:8606276350 CR:JAGae40428 )
	The device identifier for the Intel ICH4 chipset changed in
	the last version of the Intel OEM i870 hardware.

	Resolution:
	The IDE ICH4 chipset device identifier changed in the IDE
	driver.

	( SR:8606271532 CR:JAGae35740 )
	An IDE IO completes at the same priority as the process
	that started it.  A non-realtime process can block waiting
	for a realtime process.

	Resolution:
	The IDE driver now completes IOs in the context of the
	interrupt handler, which runs at higher priority than
	realtime processes.

	( SR:8606270190 CR:JAGae34428 )
	In some error cases, an IDE IO could take longer than the
	"ioscan" command allows.

	Resolution:
	Change the IDE driver's method for error handling and
	IO completion, reducing the amount of time that an IO takes
	to finish.

Enhancement:
	No
