The MESH issue looks like a buffer alignment problem, and worked > without complaint in the 2.4 kernels. It's a problem. The SCSI stack is passing us unaligned buffers when slab debugging is enabled, thus triggering a HW issue with those unaligned buffers (the chip writes before the beginning of the buffer) > The video mode problem is a real nuisance and is the biggest reason i'm not > doing more than intermittent testing of 2.6.0/PPC. I'd appreciate if you could track it down as I won't have access to the 8500 for a few weeks still. > -- JM > > > P.S.
