1 Kernel I/O error in centos

For user's using red hat  enterprise linux  centos   v5 ..  it give's  a  Journal  commit  I/O error over terminal   after  running  O.S. from 4 mins to 4 hrs. any time only in few  systems  .. (this is  due to deprived hardware support )  .This is  big problem . I   consulted many  service centers  .after replacing all  hardwares  the problem was unresolvable ..

Solution    :-

1) boot your  O.S.  with that  errorful   kernel  and open terminal  and type ..


uname   -a       and   press enter ...

2) This wiil give you the current kernel details like version  etc  .. note down the  current kernel  version .  now     download the 2.6.17.8 kernel version using wget , enter:

$ 
wget http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.17.8.tar.gz
