btw, I've just tested this patch series: <http://lists.openwall.net/netdev/2015/04/06/19>
which in my testing prevents very hard lockups under networking load: in 3.18 and below they only seem to happen to lan1741 ports, but in 3.19+ they happen on all ports. Because this lockup is in the rx interrupt handler, nothing gets logged, not via the netconsole (obviously), but also not onto the disk or over the serial console, because the machine's sole CPU is too hung to do anything. The only way to escape is the watchdog (or pulling the power). After this patch, things look to be working as well as on the BSDs: no lockups. If it doesn't hit -stable (and thus 3.19), it should at least land in kernel 4.1 and above. -- NULL && (void) _______________________________________________ Soekris-tech mailing list [email protected] http://lists.soekris.com/mailman/listinfo/soekris-tech
