Message-ID: <13bb628102314f509629bb399b056eb9@EX132MBOX1A.de2.local> Date: Wed, 14 Jan 2015 08:38:03 +0000 From: "Stoidner, Christoph" <c.stoidner@...ero.de> To: "Stoidner, Christoph" <c.stoidner@...ero.de>, "paulmck@...ux.vnet.ibm.com" <paulmck@...ux.vnet.ibm.com> CC: "linux-kernel@...r.kernel.org" <linux-kernel@...r.kernel.org> Subject: AW: Question concerning RCU Hi Paul, > Two things to try: > > 1. alt-sysreq-t to get all tasks' stacks, or I am not able to do that since I am working on an embedded system which has no real tty, just a serial connected terminal. > 2. disable RCU CPU stall warnings and see if the hangs go away. > As I see there is no config option to disable stall warnings. So I have now removed the calls of print_cpu_stall() and print_other_cpu_stall() in check_cpu_stall() in rcutree.c. Now the system crashs after some run-time with the kernel message you can find at the end of that mail. > Hmmm... Are you by chance pushing all dmesg through a serial console? What exact do you mean? I thought I can see already all messages on my kernel console. Do you think some message was chocked on some reason? > One thing to try would be to add a counter and break out of the loop > after (say) 10 iterations. Is that a change you are comfortable making? I will do so and give you the results. So now here is the kernel output mentioned from above (messages when crash with disabled print_cpu_stall and print_other_cpu_stall): [ 3448.269140] WARNING: at kernel/rcutree_plugin.h:227
