Hi, can anyone possible give a list of known stable kernel versions for SPARC machines? (is there a difference necessary between architectures/old vs. newer machines? sun4u/sun4v)?
Also this instability manifests such that the machine is crashing during high workload? (halting? rebooting?) I ask, because on three different SPARC machines i have been experiencing a weird effect when using debian: I would start a high compiling load for several days (7-10) where the machines are running fine without any apparent error visible in dmesg or somewhere else. Then when i power off tand on again, the filesystem would be corrupt and sometimes impossible to repair without reinstallation. This seems to only happen when the machines do a long run with high workload and seemingly not when i just power them off again for night with no high workload.
