I can't make up the MTD version out of your kernel version. Would it be the 
last CVS for 2.4.x from March 2005, or older?

Can you turn debug-level to 1 in the jffs2 (and mtd) driver and post (relevant 
parts of) console output here? I'm not sure if I can help, but MTD developers 
might want to see what the kernel is busy with for so long.
I personally want to know if it has any relation with the architecture you are 
running on. I have had problems in the past with 2.4.x on PowerPC and older 
versions of MTD. Since I changed to CVS-march2005 I have not had any trouble, 
but I want to know more, and I need to be as sure as possible that I will not 
have any more trouble. The problem is, this kernel version is not officially 
supported anymore by mtd developers, so we are a little bit left out in the 
cold if there is trouble.

Best regards,
