Also, a kernel config option would make this parameter obvious to everybody. I had only a small preformance decrease from 16 to 8 tags (well, disk IO sucks anyway under linux-pa and my old box). While 2 is pure sufference :) > And you are sure that scsi id are well different and scsi chain well terminated, I supose. Yes, the internal chain is terminated with the original HP terminator and I removed the disk internal ones. In fact substituing the original HP disk with another one removed the problem (strangely enough, with the older IBM drive as a second drive I had sometimes freezes but this problem did not appear). > hmm, I leaved the same experience but with two external disks of exactly the same type (same supplier: hp, same manufactor: > seagate, same product reference) but with a small firmware revision difference. Unfortunately, this pb only occured under linux > :(. Now the disk is broken again; so no chance to test it with more recent kernel 2.4 or 2.6 :( I used a failry recent kernel for there test, I believe 2.4.23. The scsi code doesn't seem to be so stable and performing as compared to hp-ux.... -Ric
