| |
2.6.30-stable review patch. If anyone has any objections, please let us know.
------------------ From: Kashyap, Desai <kashyap.desai@lsi.com>
commit be9e8cd75ce8d94ae4aab721fdcc337fa78a9090 upstream.
Inhibit 0x3117 loginfos - during cable pull, there are too many printks going to the syslog, this is have impact on how fast the interrupt routine can handle keeping up with command completions; this was the root cause to the config pages timeouts.
