  I have merged the latest JFFS2 filesystem, mtd
drivers and block drivers on my 2.4.7 timesys linux
kernel. The snap shot I have used for merging is
"mtd-snapshot-20040527.tar". I am running this kernel
on my 8270 Powerpc board with AM29LV128ML flash chip.
The bus width is 32, interleave is 2 and flash size is
32M. The kernel boots up with JFFS2 as the root file
  All the file operations such as list, copy and
delete are working fine. Finally when I issue a
shutdown to boot  my board I get an exception:
floating point used in kernel (task=c5158000,

The same kernel with 1.5 years old snapshot of JFFS2
works fine. Any idea what could be the issue.

Thanks in advance.
