Hello,
we use Kernel 2.6.30.4 on a PXA270 platform (from Phytec). It works good
with all peripherals on the Phytec board.
For an old Sandisk device (diskonchip) we have a driver ported to 2.6.3x
as the block device driver API has changed. We thought it will be a wise
decision to do the porting already to 2.6.3x.
However, when using the latest Kernel (and the previous one 2.6.30) with
all the drivers we used in 2.6.30.4 udev and usb storage seem not to
work any more.
Does anybody have an idea why?
Thanks,
Marco

I think you need to report this to the USB/udev people.

No, I don't. Do you have a pointer to your code anywhere?

Hello Greg,
I attached the patch and the .config for our pxa board. The largest part
is the tffs driver, the board specific things are very little.
This patch and the .config work for 2.6.30.4 except this tffs sandisk
block device driver. Per default the driver is not compiled into the
kernel so I think it is not affecting the behavior I am facing.
I tried now the latest stable kernel 2.6.31.2.
After downloading the kernel I patched the kernel sources and used the
attached .config for building the kernel.
I get still the same errors and backtrace messages.
Both times the kernel oops happens when the PC is in the strlen
function.
Any hints on how to debug this?
Thanks,
Marco

Hello Greg,
I attached the patch and the .config for our pxa board. The largest part
is the tffs driver, the board specific things are very little.
This patch and the .config work for 2.6.30.4 except this tffs sandisk
block device driver. Per default the driver is not compiled into the
kernel so I think it is not affecting the behavior I am facing.
I tried now the latest stable kernel 2.6.31.2.
After downloading the kernel I patched the kernel sources and used the
attached .config for building the kernel.
I get still the same errors and backtrace messages.
Both times the kernel oops happens when the PC is in the strlen
function.
Any hints on how to debug this?
Thanks,
Marco

Ick, what is wrong with the existing disk-on-a-chip support we have in
Linux?

I do not know, sorry. It's very strange.

It looks that more things which worked with 2.6.30.4 do not work with
the latest stable 2.6.31.2 kernel. I get also a Kernel oops when
rebooting the system.
What I did to get there:
I disabled udevd and made the important device nodes static. This
allowed to boot into the system. I also disabled unnecessary things like
USB support and the tffs disk-on-chip driver.
Starting udevd manually does cause the same kernel oops as described at
the beginning of this thread.
In addition I get that oops when rebooting the system:
/ # reboot
The system is going down NOW!
Sending SIGTERM to all processes
Sending SIGKILL to all processes
Requesting system reboot

I think something else is going on here that is a problem.
Can you turn on debugging for the driver core (CONFIG_DEBUG_DRIVER) and
let us see the kernel log? I'm guessing that you have a driver that
doesn't like some of the driver core changes that went into 2.6.31.

See my response to you on the linux-hotplug list for a number of bugs I
just found in the driver code you posted. In short, it's your code, not
the kernel :)

The failure was caused by:
static struct isp1760_platform_data isp1760_platform_data __initdata = {
__initdata causes a section mismatch and finally a kernel oops. So it
was driver related not as I thought an udev issue. Strange that this
behavior didn't show up in 2.6.30.4.
Cheers,
