All,

I've now tested the following;

2.6.17-rc6-mm2 with the following patch applied;
---
git-acpi.patch from ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.17-rc6/2.6.17-rc6-mm2/broken-out/
---

With no difference to the end-result.

Next I stripped out 802.11 generic support and acx111 drivers from the kernel (including the acpi patches) to check if it clashes, but the same errors occur....

Thirdly, I booted with acpi=off on the command line with two kernels, the stock 2.6.17-rc6-mm2 (no acpi patch and including acx111) and the one including the acpi patch and no acx111, the results were;

acpi_patch;
works a treat, picks up USB devices as expected.

stock;
works a treat, picks up USB devices as expected, and my acx111 card works too :)


Now I'm looking for good suggestions again, this definitely looks like it is related to ACPI, hence the cc' to that list too, as requested by Andrew M.

I'm happy to apply patches / config changes as appropriate and for those who may ask for my .config files, please see;

Also, I left the output of lspci there for reference;

Cheers,

It's appropriate.

I tried the kernel list with zero responses (so far ;), let me know if there is
anywhere else this should go.

All,

My USB hub isn't recognised with the latest -mm series, whereas with
2.6.16 vanilla it is picked up & used immediately.

The error I get in dmesg is;

hub 4-0:1.0: USB hub found
hub 4-0:1.0: 2 ports detected
usb 1-4: new high speed USB device using ehci_hcd and address 3
ehci_hcd 0000:00:10.3: Unlink after no-IRQ?  Controller is probably
using the wrong IRQ.
That last line is a clue.  What interrupt numbers are assigned under
2.6.16?  If you unplug the SonyEricsson DCU-11 Cable before booting (and
leave it unplugged), what shows up in /proc/interrupts for both versions
of the kernel?
See attached, both with the DCU-11 cable disconnected.

There's nothing obviously wrong.

Most likely this is a problem with the ACPI subsystem, not a USB problem.

I guessed USB due to the number of USB changes in the -mm series and, obviously, my USB devices stopped registering, however, I'd not know one from the other ;)

What happens if you boot with "acpi=off" on the boot command line?
