It feels as though something is blocking upon file access to my Drobo Firewire 800 unit, however it happens at a seemingly consistent rate. If I boot from the Drobo unit pauses happen continually, however if I simply am accessing it from a Macbook Pro on my Mac Pro with the Macbook Pro in Target mode then it appears to happen at more irregular intervals. The folks at Drobo have basically said it should work fine and don't really seem to be too helpful and I am really struggling tracking this down as I am not 100% convinced that it is a device related issue. I did have some bad blocks on a drive and have replaced it, all else SEEMS to check out okay on this Mac Pro. I was hopeful to get some tips on this list as to what I should do next so as to ascertain the source of the problem. I am not even sure where to profile or how to poke in this situation as it is so irregular. This email sent to site_archiver(a)lists.apple.com

The Darwin Team is proud to announce the release of the Darwin open source components of Mac OS X 10.6 and Xcode 3.2. They are available at the usual location below. We are still processing some projects, and did not want to hold up the bulk of the release, so the following projects are coming later: This email sent to site_archiver(a)lists.apple.com

Hi Rick, Unfortunately, no. Snow Leopard (Darwin 10) has more/better NFSv4.0 support but it is not considered "production quality" yet. New in Snow Leopard are support for open and lock state management, state recovery, some initial delegation handling support and callbacks. Oh, and Kerberos should now work with NFSv4 too.

IOMemoryDescriptor::writeBytes Kernel Panic
by Duane Murphy 27 Aug '09

27 Aug '09

site_archiver(a)lists.apple.com Delivered-To: darwin-kernel(a)lists.apple.com -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Our disk kext is seeing a random kernel panic when simply calling writeBytes with an IOMemoryDescriptor. ... status = requestBuffer->prepare(); if ( status != kIOReturnSuccess ) { // Exit } requestBuffer->writeBytes( 0, buffer, bufferLength ); requestBuffer->complete(); ... The system where we are seeing this crash is using software RAID. The back trace shows IOMemoryDescripor::writeBytes (an address in AppleRAID) IOGeneralMemoryDescriptor::getPhysicalSegment IOGeneralMemoryDescriptor::dmaCommandOperation and then panic. The kext is simply copy data that was retrieved from the disk into the memory descriptor. The source buffer is from another memory descriptor. This descriptor was created using IOBufferMemoryDescriptor::inTaskWithPhysicalMask. The physical mask limits the memory to the 32b range. It seems like the AppleRAID driver is using a custom memory descriptor (which is reasonable and common) but is not handling some situation that we are presenting to it. Any ideas what we could be doing wrong here?

Is NFSv4 in Snow Leopard?
