I posted this question some month ago, got no replies. I recently
repeated the installation with FreeBSD 6.2 and got the same results.

STATEMENT OF PROBLEM
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
FreeBSD 6.1 runs very slowly out of the box on my MS-1029 AMD Turion
notebook computer. The first line from the output of 'ps -aux' tells
that interrupt 19, in use by the ohci and cardbus systems, is consuming
80% of the CPU time:
USER PID %CPU %MEM VSZ RSS TT STAT STARTED TIME COMMAND
root 21 79.1 0.0 0 16 ?? LL 11:52AM 25:48.51 [irq19:
cbb0 ohci
ATTEMPTED RESOLUTIONS
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
I attempted to disable the affected devices in the boot configuration
file "/boot/device.hints." In all cases my 'hints' were ignored and
the device drivers were loaded as normal. I also tried to do the
equivalent with sysctls, also to no avail (though I might be doing the
Wrong Thing):
hint.ohci.0.disabled=3D"1"
hint.usb.0.disabled=3D"1"
hint.cardbus.0.disabled=3D"1"
hint.pccard.0.disabled=3D"1"
Booting in safe mode and with ACPI disabled did not help.
I rebuilt the kernel with the cardbus driver disabled. This caused the
cardbus to disappear from the problem interrupt but the ohci driver was
still using irq19 and was having an interrupt storm. In the
compromised state of my computer it takes 48 hours to compile a kernel,
I don't have access to another computer and anyways I need USB support,
so I don't want to recompile again without USB support.
I installed FreeBSD 6.0 and the problem was the same. I installed
FreeBSD 5.3 and there was no problem (except that I needed to disable
ACPI), nor was there a problem with NetBSD 3.0, nor Linux 2.4 or 2.6. =
OpenBSD 3.9 also appears to suffer from an interrupt problem.
DETAILED INFORMATION
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
The computer is a Microstar MS-1029 with an AMD MT-37 Turion
processor running at 2.0ghz.
The Motherboard uses an ATI Radeon Xpress 200P Chipset (North Bridge
RX480M, South Bridge SB400).
The Graphics Card is an ATI Mobility Radeon X700 with 128 MB of
dedicated RAM.
The system has 1024 MB of memory. The BIOS is "A1029AMS v2.70"
I used the minimal installation from 6.1-RELEASE-amd64-disc1.iso
# uname -a
FreeBSD 6.1-RELEASE FreeBSD 6.1-RELEASE #0: Sun May 7 04:04:14 UTC
2006 root@bloom.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC amd64
see below for dmesg output.
Windows XP reports the following information regarding IRQ 19:
IRQ 19 Standard OpenHCD USB Host Controller OK
IRQ 19 Standard OpenHCD USB Host Controller OK
IRQ 19 Standard Enhanced PCI to USB Host Controller OK
IRQ 19 Ricoh R/RL/5C476(II) or Compatible CardBus Controller OK
The results of running other operating systems on the computer:
FreeBSD 6.1 -! ohci (USB) and cardbus interrupt storm on IRQ 19
FreeBSD 6.2 -! identical problem =
FreeBSD 6.0 -! identical problem
FreeBSD 5.3 -- ACPI crashes on boot. No interrupt storm when booted
w/o ACPI, kernel ignores spurious interrupt on IRQ 7
NetBSD 3.0 -- no problem
OpenBSD 3.9 -! Apparently the same problem as with the FreeBSD 6
kernels... interrupts use 80+% of the cpu; the
individual interrupts are not listed by ps... I don't
know much about OpenBSD so I can't say more.
Slackware 9.1 with Linux 2.4 kernel -- no interrupt problem (but disk
access is slow, probably an old ATA driver)
Slackware 11 with Linux 2.6 kernel -- no problem
WindowsXP Professional with SP2 -- occasional spurious 'data'
returned by ACPI hardware, runs fine otherwise.
When I first installed FreeBSD 6.1, the install program ran fine, and
at the end of the install process I checked the state of the processes
using the holographic shell; there was no interrupt storm.
When I tried booting my system using the install disk as a rescue disk,
the system suffered from the same interrupt storm (perhaps there is a
significant difference between the "install configuration" and the
"rescue configuration")?
I noticed in the boot process that the computer appears to run fine
through the initial boot, but at around the point that it begins
processing the rc files it slows down. The slowdown appears to begin
between "module_register_init: MOD_LOAD (amr_linux, 0xffffffff806205d0,
0) error 6" and "Entropy Harvesting:"; in particular, the slowdown
first appears noticeable when the ATA devices were probed (but this may
just be due to waiting for devices to respond). Following up on this
observation, I disabled entropy harvesting of interrupts but this did
not help. Windows reports this about the IDE/ATA system:
Name Standard Dual Channel PCI IDE Controller
Manufacturer (Standard IDE ATA/ATAPI controllers)
Status OK
PNP Device ID PCI\VEN_1002&DEV_4376&SUBSYS_02911462&REV_00\3&267A616A&0&=
A1
I/O Port 0x0000FF00-0x0000FF0F
Driver c:\windows\system32\drivers\pciide.sys (5.1.2600.0
(XPClient.010817-1148), 3.25 KB (3,328 bytes), 8/3/2004 9:07 PM)
Windows also reports an occasional error from the ACPI hardware:
\Device\ACPIEC: The embedded controller (EC) hardware didn't respond
within the timeout period. This may indicate an error in the EC
hardware or firmware, or possibly a poorly designed BIOS which accesses
the EC in an unsafe manner. The EC driver will retry the failed
transaction if possible.
This is all the headway I've been able to make, sorry I wasn't able to
pinpoint the problem.
