Could this be related to the IDE issues that have been discovered with my hard drive? This would mean that there could be a bug in the way DMA is implemented in hardware on the wallstreet motherboard. It has been mentioned its possible. (small flashback: corruption on occation when playing sound, often ro programs when executed (vi got hit; would run, but would error. few flipped bits probably), mentioned in SoundJam's readme. 'Contact Apple') Since MacOS doesn't seem to have any of these problems, there is a solution. my hard drive from dmesg: hda: IBM-DYLA-28100, ATA DISK drive hda: IBM-DYLA-28100, 7815MB w/459kB Cache, CHS=15880/16/63, (U)DMA Since my brother's lombard has a Toshiba HD, could this all be funkyness with IBM drives, God forbid? (as opposed to just the BMAC+ doesnt have the hw bug) Before we start being suspicious, anyone with a non-IBM drive having this problem? -- Joseph P.
