Warning! ehci_hcd should always be loaded before uhci_hcd
Bit Twister
which results in interrupts are disabled.
Does anyone have a suggestion on how I can get ehci_hdc loaded before
ohci_hcd ?

Have a look in /etc/modprobe.conf
Bit Twister
Looked good to me, but dmesg shows otherwise.
$ cat /etc/modprobe.conf
install scsi_hostadapter /sbin/modprobe pata_atiixp; /sbin/modprobe sata_sil; /sbin/modprobe sbp2; /bin/true
install usb-interface /sbin/modprobe ehci_hcd; /sbin/modprobe ohci_hcd; /bin/true
options snd slots=snd_atiixp,snd_hda_intel
options ipv6 disable=1
Benny Nielsen
Yah right I changed to:
install scsi_hostadapter /sbin/modprobe pata_sis; /bin/true
install usb-interface /sbin/modprobe ehci_hcd; /bin/true
install usb-interface /sbin/modprobe ohci_hcd; /bin/true
alias sound-slot-0 snd_emu10k1
and got same dmesg warning.
There is a bug report on this: https://qa.mandriva.com/show_bug.cgi?id=46969
Bit Twister
Yes, I had read about that before posting. I was hoping for an easy
configuration file change.

Solution to force ehci_hcd loading before my ohci_hcd module,
create /etc/modprobe.preload.d/usb-load-ehci-first with
install ohci_hcd /sbin/modprobe ehci_hcd ; /sbin/modprobe --ignore-install ohci_hcd $CMDLINE_OPTS
Sadly, still get stack trace, Disabled IRQ 19 and interrupts switched to
polling mode. :-(
Current modprobe setup:
# cat /etc/modprobe.preload.d/usb-load-ehci-first
install ohci_hcd /sbin/modprobe ehci_hcd ; /sbin/modprobe --ignore-install ohci_hcd $CMDLINE_OPTS
# cat /etc/modprobe.conf
install scsi_hostadapter /sbin/modprobe pata_atiixp; /sbin/modprobe sata_sil; /sbin/modprobe sbp2; /bin/true
install usb-interface /sbin/modprobe ehci_hcd; /bin/true
install usb-interface /sbin/modprobe ohci_hcd; /bin/true

From Googling, you aren't the only one having p[roblems with this, but
no real answers, e.g.:

Sorry, but it is way over my head.

After you make the changes to get ehci to load first, the initrd
has to be rebuilt ...
lsinitrd /boot/initrd-2.6.31.13-desktop-1mnb.img |grep hci

-rw-r--r-- 1 root root 30237 Apr 27 21:22 lib/modules/2.6.31.13-desktop-1mnb/ehci-hcd.ko.gz
echo "Loading ehci-hcd module"
modprobe -q ehci-hcd
echo "Loading ohci-hcd module"
modprobe -q ohci-hcd
echo "Loading uhci-hcd module"
modprobe -q uhci-hcd

Pardon my ignorance, but I thought the modprobe directories/files were
to load items not in the image.

That's true, however with Mandriva, the usb modules will normally
be put in the initrd, and loaded based on the order in the
config files when the initrd was created.
Changing the config files after the initrd is created doesn't change
the order of the loading in the initrd init script.
When the real init program tries to load them based on what is in
the config files, it'll find they are already loaded (by the initrd
init script), and will just ignore the config file entries.
Try running ...
lsinitrd /boot/initrd-2.6.31.13-desktop-1mnb.img|grep hci
to confirm if the initrd init script is loading them, and in what
order.
To update the initrd, after changing the order in the config files, ...
mkinitrd -f /boot/initrd-2.6.31.13-desktop-1mnb.img 2.6.31.13-desktop-1mnb
Confirm the order has been changed using the lsinitrd command.

Not on 2010.1 beta 2 :
