The bug you listed was fixed in 5.0.19.
> System configuration:
> Adaptec 2842VL (Narrow Fast SCSI)
>
> SyQuest SQ3270S (Narrow SCSI)
> Plextor PX-32TS (Narrow Ultra SCSI)
> Micropolis 4345WS (Wide Ultra SCSI)
>
> With 5.0.14 (as of plain linux-2.0.34) and aic7xxx=no_reset, everything
> seems to be fine at first glance.
>
> With 5.0.18, the driver properly detects it has a narrow channel VLB host
> adaptor, but negotiates 16-Bit wide transfers with the Micropolis. This must
> fail, since it's an 8 bit wide bus.
>
> Thus, the kernel deletes the corresponding disk entry sda "illegal sector
> size" (something around 16 million) and crashes with an "invalid zero
> pointer dereference", followed by an oops. I cannot currently trace the
> oops, I am setting up the machine for serial console controlled boot-up the
> next days.
>
> Patching aic7xxx_parse_msg to always use 8-Bit transfers did not help
> either, it led to bus resets and kernel panic (since it could not mount its
> root partition).
