Bug#613172: reportbug: samba/kswapd0/ext4 moving large files or causing high systemload cause kernel panic/system freeze
Package: reportbug Version: 4.12.6 Severity: critical Tags: lfs Justification: breaks the whole system This problem started when i updated to Squeeze from Lenny, which never portraited this issue. When i try to put the system under quite some load by either compiling with make -j3 (dualcore system) or move a +40GB file through samba on an ext4 fs using a 1Gbit NIC the kernel throws a trace and freezes, compiling my own kernel (2.6.37) enabled me to do a regular reboot now, but it is rendered unusable from there on after untill i reboot the machine. I have been unable to trace the problem to one specific thing, it might be kernel related as this and the debian squeeze kernels are newer then the one i used before. I have trace information and system information at the ready for anyone who wishes to view them. Kernel/Debian developers can use my system to debug if needed. I hope you can help, i'll be forced to return to Lenny if this cant be resolved... and that would be a shame... Squeeze looks good from many perspectives! Regards, Barry Schut a.k.a.

Bug#613172: The gziped systeminformation
Tried blacklisting rl2870sta and unfortunately it did not really help... So far I have been able to get it to crash (every time I attempt these actions, so 100% reproducible): Mkfs.ext3/4 /dev/sdc5 (which is a 1TB SATA disk) Make -j3 bzImage make -j3 modules The same happens when I transfer a 48GB windows backup system image to a samba share. The grand unifier in these actions is that they put a strain on both SMP/CPU load and disk I/O. The system throws a trace to the console and freezes using 2.6.32-5-amd64. Using a custom kernel I manage to overcome the initial freeze, but a reboot remains mandatory. I can provide you with login details if you want to take a look, I'll grant you any help you need, you can install whatever you need even if that means I need to reinstall the system.

You might try blacklisting the wireless driver since your earlier traces showed it breaking. I'm confused though. You said you had troubles with moving large files with samba. That wouldn't affect the boot, so you should still have a log somewhere. Cheers, Julien -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe. Trouble?
