Floating point exception

[kas turi]

Hi
  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
system.
  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,
pc=ff000104)
Oops: Exception in kernel mode, sig: 4

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

Thanks in advance.
