| |
Hi all, I have been having problems with the developmental scsi support(since at least before 1.128 through 220p8). This problem has been recurrent on both adaptec 7880's and ncr53c875's. Basically everything is fine until I put a heavy load on the adapter-ie a stripe across 5 or more drives. Then I get a series of timeout related errors-see below.. I have reduced queue tags to zero, but I still get this problem. I have tried on multiple systems(dual vectra xu p6's, dual p2 compac 1600's, hp netservers lh II's-all with their own adapters), and they all have similar timeout problems-that hang the system for 10 secs or more before resetting. The only kernel I haven't had problems with is the out of the box redhat 5.2(v2.0.36)-which is very slow for scsi-and if I recompile that one, I get a system hang on the scsi timeout. I was wondering if anyone has had a similiar problem, and could tell me what changes to make in the scsi code, so that either I won't get this problem, or the timeout and reloading the scripts into the controllers memory won't take so long(it may be a bottleneck anyways)... thanks
