It's hard to figure out what's going on with your system for several reasons. For one thing, you've mentioned at least 3 different peculiar behaviors. For another, you posted logs with lots of extra information that tends to hide the important parts. And also you have lots of USB devices, which makes it hard to see what's happening with the iPod. So here's what I want you to do. To begin with, unplug _all_ your USB devices. Then do "dmesg -c >/dev/null" to clear the kernel log buffer. After waiting a few seconds, plug the iPod in to the computer. After a few seconds, make a copy of /sys/class/usb_host/usb_host1/registers. Then unplug the iPod. After waiting a few more seconds, plug in your hub. Wait a few seconds and then plug the iPod into the hub. After a few seconds, make another copy of /sys/class/usb_host/usb_host1/registers. Then unplug the iPod and the hub. Finally, get a copy of the dmesg log. After having done all that, repeat it exactly but this time using a version of ehci-hcd with that patch reverted. Post everything and we'll see how it looks.

Hi, this is the bisect result: $ git bisect good 1d619f128ba911cd3e6d6ad3475f146eb92f5c27 is first bad commit commit 1d619f128ba911cd3e6d6ad3475f146eb92f5c27 Author: Marcelo Tosatti <[EMAIL PROTECTED]> Date: Sun Jan 21 19:45:59 2007 -0200 USB: switch ehci-hcd to new polling scheme Switch ehci-hcd to use the new polling scheme, which reports root hub status changes via the interrupt handler, in an asynchronous fashion.

Instructions for bisecting:
<-- snip -->
# install git and cogito on your computer
# clone Linus' tree:
cg-clone \
git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git
# start bisecting:
cd linux-2.6
git bisect start
git bisect bad v2.6.21-rc4
git bisect good v2.6.20
# start round
cp /path/to/.config .
make oldconfig
make
# install kernel, check whether it's good or bad, then:
git bisect [bad|good]
# start next round
After at about 12 reboots, you'll have found the guilty commit
("... is first bad commit").
More information on git bisecting:
man git-bisect
<-- snip -->

So can you bisect to find what caused the problem? We've been afflicted with such strange overcurrent messages off and on for some time. Some hardware triggers them, while most doesn't, and the USB developers don't have any of the hardware that triggers it (that almost goes without saying). It's been clear to me that _something_ the software does is making that more likely to happen. One thing we've been lacking is anything like a usable clue as to what kind of changes would have that failure mode ... and thus, what kind of changes could remove it. - Dave - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
