(interleaved chips) cfi_cmdset_0002 -> Kernel Panic

[Oliver Korpilla <okorpil@fh-landshut.de>]

Hello!

In recent posts it is mentioned that there is a kernel panic like this:

/ # cat tmp/rootfs.jffs2.img > /dev/mtd0
Waiting for write to complete timed out in do_write_oneword.Scheduling 
in interrupt
kernel BUG at sched.c:564!

Kernel panic: Aiee, killing interrupt handler!
In interrupt handler - not syncing

It is happening because of the broken AMD command set for chips like 
mine (at least as far as I understand it from pretty recent posts to the 
list). I have the following startup with kernel.org 2.4.25:

physmap flash device: 300000 at ff000000
CFI: Found no Physically mapped flash device at location zero

Found: AMD AM29LV800BT
Physically mapped flash: Found 4 x16 devices at 0x0 in 32-bit mod

It wouldn't work with a recent patch from the CVS snaphost downloads, 
because auto detection won't work. AFAIK it is broken.

How are the chances of fixing it? Is there a working version "out there" 
that supports my flash chip, auto detection and works?? Is there a 
quickfix I could apply (increasing some timeout value, copying over 
another implementation of that do_write_oneword function)???

Thanks in advance,
