Howdy,
I'm running 3.0-release (and impatiently waiting for the 3.0-stable
release tomorrow.. :-) on an SMP box with an Adaptec 3940AUW on the Tyan
S1836DLUAN motherboard. I've installed a DPT PM2654U2-R with 16MB of cache
RAM in the system also, but I can't get the kernel to recognize my hard drive
when it is trying to mount root, near the end of the booting process. It
gets as far as saying "changing root device to da0s1a" and then whines about
not finding the drive to mount as root. This is weird to me, since it's gotten
this far by reading the kernel from the drive.. :-? I've attached my kernel
config file below, can anyone point out any obvious problems? Perhaps this is
already fixed in the current->stable tree and I can just download the stable
source tomorrow when it's released? (knock on wood :-) I'm currently running
fine (but slower than I want) from the on-board Adaptec controller.
Thanks for any help,
Quincey Koziol

# The 'dpt' driver provides support for DPT controllers (http://www.dpt.com/).
# These have hardware RAID-{0,1,5} support, and do multi-initiator I/O.
# The DPT controllers are commonly re-licensed under other brand-names -
# some controllers by Olivetti, Dec, HP, AT&T, SNI, AST, Alphatronic, NEC and
# Compaq are actually DPT controllers.
#
# See sys/dev/dpt for debugging and other subtle options.
# DPT_VERIFY_HINTR Performs some strict hardware interrupts testing.
# Only use if you suspect PCI bus corruption problems
# DPT_RESTRICTED_FREELIST Normally, the freelisat used by the DPT for queue
# will grow to accomodate increased use. This growth
# will NOT shrink. To restrict the number of queue
# slots to exactly what the DPT can hold at one time,
# enable this option.
# DPT_MEASURE_PERFORMANCE Enables a set of (semi)invasive metrics. Various
# instruments are enabled. The tools in
# /usr/sbin/dpt_* assume these to be enabled.
# DPT_FREELIST_IS_STACK For optimal L{1,2} CPU cache utilization, enable
# this option. Otherwise, the transaction queue is
# a LIFO. I cannot measure the performance gain.
# DPT_HANDLE_TIMEOUTS Normally device timeouts are handled by the DPT.
# If you ant the driver to handle timeouts, enable
# this option. If your system is very busy, this
# option will create more trouble than solve.
# DPT_TIMEOUT_FACTOR Used to compute the excessive amount of time to
# wait when timing out with the above option.
# DPT_DEBUG_xxxx These are controllable from sys/dev/dpt/dpt.h
# DPT_LOST_IRQ When enabled, will try, once per second, to catch
# any interrupt that got lost. Seems to help in some
# DPT-firmware/Motherboard combinations. Minimal
# cost, great benefit.
# DPT_RESET_HBA Make "reset" actually reset the controller
# instead of fudging it. Only enable this if you
# are 100% certain you need it.
# DPT_SHUTDOWN_SLEEP Reset controller if a request take more than
# this number of seconds. Do NOT enable this
# unless you are really, really, really certain
# you need it. You are advised to call Simon (the
# driver author) before setting it, and NEVER,
# EVER set it to less than 300s (5 minutes).
