Hello, I got a Kernel panic by some long time stress tests. Look here: http://dy.cx/pqP7M. Furthermore I got sporadic some BUG messages: [ 1128.358971] BUG: scheduling while atomic: swapper/0/0/0x00010002 [ 1128.358982] Preemption disabled at:[<ffffffff810dfb8a>] cpu_startup_entry+0x17a/0x300 Hardware -------- My system is a i7 with 4 GB RAM congatec evalboard. Setup ----- On the system runs Linux RT (text mode) 3.10.10-rt7 with 1 GB RAM and a Windows 7 KVM/QEMU (Qemu 1.6.1) guest with 3 GB RAM. Each system has it own ethernet card. The Win 7 guest uses it per pci pass-through. The Win 7 is pinned to core 2,3. Scenario -------- We sending UDP packages every 1 msec on the Linux side. The UDP sender process has real time prio 80 and the ethernet driver 90. At the same time we are stressing Win 7. Memory stress - allocate as much as possible and do memset(), then CPU stress - high CPU load, then Kernel DPC stress - high load thread at DPC level and ethernet stress - send UDP packages every milliseconds. I got the panic after 45 minutes. It seems that is correlates with the ethernet stress. Can anybody help me? thanks Jens -- To unsubscribe from this list: send the line "unsubscribe linux-rt-users" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
