Hi,

The following bug exists in 2.6.32-rc* also.

 > ------------[ cut here ]------------
 > Kernel BUG at 000003e00429d934 [verbose debug info unavailable]
 > fixpoint divide exception: 0009 [#1] SMP

Please find the patch which solves the following 'fixpoint divide 
exception'. I tested the same and not seeing any KERNEL BUG/exception.

I created the patch from 2.6.32-rc6 code.


Thanks and Regards

Though the 'sbi->s_log_groups_per_flex' contains valid data after the 
shift operation 'groups_per_flex' is becoming zero, which later used as 
a divisor.
groups_per_flex = 1 << sbi->s_log_groups_per_flex
