# IDE and related devices
# PCI IDE controllers - see pciide(4) for supported hardware.
# The 0x0001 flag force the driver to use DMA, even if the driver doesn't know
# how to set up DMA modes for this chip. This may work, or may cause
# a machine hang with some controllers.

# ISA Plug-and-Play IDE controllers

# PCMCIA IDE controllers

# ISA ST506, ESDI, and IDE controllers
# Use flags 0x01 if you want to try to use 32bits data I/O (the driver will
# fall back to 16bits I/O if 32bits I/O are not functional).
# Some controllers pass the initial 32bit test, but will fail later.

# IDE drives
# Flags are used only with controllers that support DMA operations
# and mode settings (e.g. some pciide controllers)
# The lowest order four bits (rightmost digit) of the flags define the PIO
# mode to use, the next set of four bits the DMA mode and the third set the
# UltraDMA mode. For each set of four bits, the 3 lower bits define the mode
# to use, and the last bit must be 1 for this setting to be used.
# For DMA and UDMA, 0xf (1111) means 'disable'.
# 0x0fac means 'use PIO mode 4, DMA mode 2, disable UltraDMA'.
# (0xc=1100, 0xa=1010, 0xf=1111)
# 0x0000 means "use whatever the drive claims to support".

# ATAPI bus support

# ATAPI devices
# flags have the same meaning as for IDE drives.

        This problem does NOT happen while testing the tape drive
	with tar(1).

	Tape drive in question is st2 in dmesg(8) output as above.

>How-To-Repeat:
	Take possibly bad tape drive; attach to AHA-1542CP for testing.
	dump all filesystems to tape until it fills.  Now rewind
	the tape, and test integrity of dumps with "restore rdN".
	While reading the 3rd tape mark, machine panics and takes
	the crash dump.
>Fix:
	Unknown.

	Perhaps try test with known good tape drive with same dump tape 
	and see if problem replicates.  Have sufficient equipment
	for such a test.
