We have 2 users with different SCSI adapters, different RAID levels (0 vs 5) running low latency kernels (both 2.4 and 2.6), and xruns associated with disk writes cannot be eliminated. The problem goes away when RAID is removed from the picture. This sounds like a problem with the kernel software RAID layer. Lee
