[Gllug] CentOS release 5.4 (Final) + Nic Bonding + machine goes out of network randomly + 2.6.18-164.6.1.el5 #1 SMP kernel

[Narender]

Sorry it does not worked in my case:(. i put the values in
modprob.conf (options bnx2 disable_msi=1)and even rebooted the server.
but it again went out of network after 1 hour.

is the kernel up gradation only option left. if yes then could someone
point me the best way to upgrade the kernel. This machine is a
production box.


Best Regards
N
