Hello,<br><br>I'm getting the following errors on the console:<br>INFO: RCU detected CPU 0 stall (t=1000 jiffies)<br>INFO: RCU detected CPU 0 stall (t=4000 jiffies)<br>INFO: RCU detected CPU 0 stall (t=7000 jiffies)<br>
...<br><br>The system is mostly unresponsive at this point. The console & ssh are unresponsive, but ping still works (Is that just the PHY responding?).<br><br>I'm pretty sure this is because I enabled NO_HZ, HIGH_RES_TIMERS, CONFIG_PREEMPT & ATMEL_TCLIB in the kernel. I've attached the .config file. I'm using 2.6.33-rc2 without the <a href="http://maxim.org.za">maxim.org.za</a> patch, and one minor socket-can patch. I'm been using various versions of this same kernel for weeks without any problems, and just today I wanted to use the high res timers so I enabled that stuff in the kernel. I'm using the at91sam9g20 processor. I don't think it matters, but the command that triggered this was "svn --version". After a reboot the "svn --version" command is fine.<br>
<br>What does this error/info mean? How is it different from a kernel panic? Have other people seen this on the at91 devices?<br><br>thanks,<br>Paul<br>
