@colin.stephane - please copy the attached patch to debian/patches and add it to series file. it fixes leafpad "Save As" crash.
Anyway the root of the problem is still unknown. I suspect hildonfm or similar, someone is traversing all the filesystem, executing FAT_IOCTL_GET_ATTRIBUTES to all the files. It seems this has been reported several times (here for example) but noone has find the root cause.
The attached patch will solve kernel crash but reboot will happen if you have watchdog disabled. In case watchdog is disabled you will have a reboot 30 seconds after "Save As" is pressed, because wd file is opened and then closed.
When I have time I will find what is the root cause of the problem.

Edit 01/09/2011 - 10:15 : pushed new one, this time I put 'fmtxpower' script in '/etc/event.d' properly, in the precedent build I made a mistake putting the file in '/etc', so for the ones that have used the precedent, please delete the file manually ...

@colin.stephane - it is your ramzswap module patch that is causing reboots, here is the backtrace

@colin.stephane - Will you please test the kernel at least once before uploading a link here. It is not only to put some patches and to leave others with reflashing and reboot loops.
And BTW where is this patch? I mean .diff file.
Here is the kernel with leafpad crash fixed an working ramzswap module.

Which you would easily catch if you insmod ramzswap.ko at least once, thus my point.

All times are GMT. The time now is 00:39.
Also I would like to ask if it is possible to install syslog (after installing kernel)
apt-get install sysklogd
and to post /var/log/syslog here after several "Save As" operations. There is additional logging enabled in the kernel, so I hope I will be able to have stack dump of buggy userland library/application
Thanks
EDIT: scratch the above, I was able to reproduce the crash, will investigate it by myself
