Hello,
We are experiencing some lockup problems with our SMP configuration. Here are the details : - The computers lockup with no relevant logs. - The kernel still replies to ping but higher level services are not responding. - After few hours (5-8), the kernel answers again and the load is around 40 then decreasing.
We manage to get some SysRq showPc output (screenshot : http://www.elonex.ch/shot/) According to the basic sysreq debugging, the problem seems to be related to the function flush_tlb_all, and it is triggered with a write or read (local or on nfs sometimes).
I looked at the LKML, and didn't find any known issues. Maybe it has been corrected but not backported by redhat ! I'll appreciate any help.
Thank you in advance.
detailed configuration : --------------- Processor : 2 x 2.8Ghz Pentium Xeon Motherboard : Intel se7501cw2 Memory : 4 x 512MB DDR 266 ECC registered Kernel : 2.4.20-31 (Redhat 7.3 with updates)
