Content-Type: text/plain; charset=us-ascii; format=flowed Content-Transfer-Encoding: 7bit Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 1267 Lines: 40 Hello ! I am running the 2.4.20 kernel on a system with 3.5 GB RAM and dual CPU. I am running bonnie accross four drives in parallel: bonnie -s 1000 -d / bdflush settings on this system: [root@dyn-10-123-130-235 vm]# cat bdflush 2 50 32 100 50 300 1 0 0 All the bonnie process and any other process (like df, ps -ef etc.) are hung in __lock_page. Breaking into kdb, I observe the following for one such bonnie process: schedule(..) __lock_page(..) lock_page(..) do_generic_file_read(..) generic_file_read(..) After this, the processes never exit the hang. At times, a couple of bonnie processes complete but the hang still occurs with the remaining processes and with the other processes. I tried out the 2.5.33 kernel (one of the 2.5 series) and observed that the hang does not occur. If I run, two bonnie processes, they never get stuck. Actually, if I run 4 parallel mke2fs, they too get stuck. Any clues where this could be happening?
