Works with kgcc.  Thank you Alan.

Comment 3 Arjan van de Ven 2001-02-01 17:23:27 UTC
I checked the sizeof() of the structure in question. It is 256 bytes, which
looks right. However, the driver assumes "layout in struct is exactly the layout
in hardware" while using bitfields and the like. Not that this behavior should
have changed in gcc 2.96, but it is very unportable still.

fixed in gcc-2.96-74.  New kernel src.rpms will buildprereq this version.
