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!
