I'm running into a problem with filename lengths greater than 7
characters.
Everything is fine until I unmount and then remount the device.

I'm running Linux 2.6.17 on a PowerPC 5200.

Any help would be greatly appreciated

Mailing lists are public domain.  I'm assuming, based on this notice,

Ideally, public lists would simply reject such messages.

They vary though.  And trapping thing for moderator approval is mean

Weird. Please reproduce with CONFIG_JFFS2_FS_DEBUG=1 and show the
(KERN_DEBUG) messages -- preferably by capturing them (without loss)
over a serial port. Please also take a snapshot of the offending image
from the flash.

I suspect a hardware driver or wiring problem.

Attached is the dmesg (jffs2_debug.txt) and the snapshot of the flash
sector (jffs2_flash.txt).  Hope that is acceptable etiquette.

... they're screwed. The dump you sent looks find -- but can you make it
print what it sees when it reads the node from the flash in
jffs2_get_inode_nodes()? That's where it seems to be screwed.

I used the JFFS2_ERROR function to debug the output and found that the
filenames are truncated in the read_direntry function.  Here is the
output.

>From looking at the offset in FLASH all the reads start on the word
0x1985e001 which looks okay.

Let me know if you need more or have any more pointers.

Ok, it already seems truncated by this point -- but can you hexdump the
buffer which was actually read from the flash?
