Hi, about a week ago I upgraded my Fuloong 6014 from Debian Squeeze (with a self-built kernel package for 2.6.39.4) to Debian Wheezy and am now running Debian's kernel from package linux-image-3.2.0-4-loongson-2f. Since then I've encountered system deadlocks every one-two days (the system in question is running continuously 24/7). Deadlock meaning, that the system does seems completely dead, even num-lock LED cannot be toggled any more (but fan is still spinning etc.). I never had stability problems on kernel 2.6.39. I did have a single deadlock when testing the debian-backports kernel package for kernel 3.2.0 on debian squeeze (but I ran that kernel only for about 2 days before upgrading to Wheezy). This looks like a kernel issue to me. Any ideas what's happening here? Any ideas how to work around the problem? Are there any settings that are known to cause problems on Loongson2f? I already sort of disabled frequency scaling by running cpufreq-set --min 800MHz --max 800MHz but that doesn't help wrt stability. How would I move forward trying to identify the cause of these lockups? So far I have seen nothing in syslog that may help to explain why the system stopped working at the exact times it did. May be related to disk activity (lockup often happen at night, while logcheck or tiger are running). cheers, David -- GnuPG public key: http://dvdkhlng.users.sourceforge.net/dk2.gpg Fingerprint: B63B 6AF2 4EEB F033 46F7 7F1D 935E 6F08 E457 205F
