Hello, > Ok. Got a panic with me present. > > [card dump] > panic: Waiting List traversal I see, since "ages" the same behaviour of "SEAGATE ST318436LW 0005" disks on 2940 an 29160 controllers, especially under "heavy" load (tar --blocking-factor=20480 copy data to and from ata-disk + tape-backup over ahc + dd on another scsi-disk ). Disabling Tagged Queueing makes them disappear. I also set correct terminaton in the adapter BIOS rather than automatic, but I doubt that is related. These are computation intensive lab servers. You might give it a try (if ever ST336607LW support tag-queuing ...) Arno
