Hello,

The trace appears to be claiming that kernel/async.c:async_new.func is NULL.

But it cannot be - it's initialised at compilation time. Unless something scribbled on it of course.

Cute. This might require a bisection search unless someone can see something which I missed?

Cute. This might require a bisection search unless someone can see something which I missed?

Well, since it's consistently repeatable, a bisection shouldn't be too painful. I'll try to do that tomorrow.

I've seen async problems with other subsystem too, maybe caused by a corruption which is fixed by:

I've applied the following patches (to try to fix other bugs) and I no longer get a BUG/OOPS although the patches might have not been the cause of the fix, but inserting the disk still doesn't works.

http://patchwork.kernel.org/patch/17199/
http://patchwork.kernel.org/patch/17025/
http://patchwork.kernel.org/patch/17039/

It now complains of: FAT: IO charset cp437 not found Which I've found a work around by:

<insert flash disk>
syslog complains: FAT: IO charset cp437 not found sudo modprobe -r nls_cp437
sudo modprobe -i nls_cp437
<remove then reinsert flash disk>
syslog complains: FAT: IO charset iso8859_1 not found sudo modprobe -r nls_iso8859_1
sudo modprobe -i nls_iso8859_1
<insert flash disk>
profit!!

So, I have to insert the disk 3 times before it works. although after that it just works, until I reboot and I have to repeat the unload/load modules.

Hello,

Hi,

Testing out .30-rc1 and usb devises don't work. I insert my flash disk and get this oops.
More information (dmesg, config, etc.) at
http://jdserver.homelinux.org/bugreports/003/

I suppose this has been fixed in -rc2 or current git. Have you tried after -rc1?

Hello,
Hi,
Quoted 3 lines
Testing out .30-rc1 and usb devises don't work. I insert my flash disk and get this oops. More information (dmesg, config, etc.) at http://jdserver.homelinux.org/bugreports/003/
I suppose this has been fixed in -rc2 or current git. Have you tried after -rc1?

Yes, this has been fixed -- close the bug.
I'm currently running .30-rc2 and all is well (except for #13067).
