Hello, I think that reading from CDROM is actually broken in 9.0-RELEASE/sparc64. On FreeBSD 8.2-RELEASE/sparc64, mounting a physical CDROM burned with FreeBSD-9.0-RELEASE-sparc64-disc1.iso and running sha256 on usr/freebsd-dist/*.txz yields the same results as listed in usr/freebsd-dist/MANIFEST. However, on FreeBSD 9.0-RELEASE/sparc64, mounting the same CDROM (using /dev/cd0), and running sha256 on the same usr/freebsd-dist/*.txz files yields completely different results: SHA256 (base.txz) = a96e255a9379ec1a58b756c3e788e34345fd79e35234925df842d700ccb10e1a SHA256 (doc.txz) = 54674bb68b111c3465b0beca8893a6b514b80e20dc22f2bbd208b992568261dc SHA256 (games.txz) = b9bedddeea549640b4f41a577f4c5f09aa29d0c3d0d4c105bc4fe7d327bf9fcd SHA256 (kernel.txz) = 661df36b4a2e87d2aa88ce998b50d48f2a91892fc288452a0282e3c092739046 SHA256 (ports.txz) = 315cbfac6f252de5209a3513a846d14650b98e2dcf99c12779ffd1d32acaa287 SHA256 (src.txz) = 6b3a4a9536b1ca2618949bb7bb44478266db551ac9f09ccfc92b5469a715f3cf This also prevents an installation of 9.0-RELEASE/sparc64 via bsdinstall from CDROM (bsdinistall says that the data sets are corrupted). I was only able to get 9.0 on that SunBlade 1500 by using a regular source upgrade from a running 8.2-RELEASE system (using usr/freebsd-dist/src.txz from that very same CDROM that checksummed correctly on 8.2-RELEASE). Just to make it clear: the CDROM media is correct and checksums correctly on 8.2-RELEASE. It doesn't checksum correctly on 9.0-RELEASE because reading from CDROM media is now (partially) broken. Just to make sure the 9.0-RELEASE sha256 program isn't at fault, I've mounted FreeBSD-9.0-RELEASE-sparc64-disc1.iso via mdconfig and run sha256 on the *.txz files again: same results as in MANIFEST. So sha256 on 9.0 itself is okay, it's only the reading from physical media that corrupts data (and prevents installation from CDROM -- funny that this passed release engineering and testing...).
