Maybe...but does ktrace always write sector-aligned sector-sized chunks? If not, /dev/rwd* probably won't even accept the writes. But I'd be surprised if this works any better than a filesystem mounted -o sync, even if the writes are suitably aligned and sized. Might be worth trying - under some circumstances even things with a low estimated chance of working are - anyway.... At this point, if I were the person dealing with this, I'd start scattering debugging in the relevant kernel code paths. /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTML mo...@rodents-montreal.org / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B
