Jesper told me a long time ago that the offsets in struct ConfigDev are wrong on the PPC due to different default alignments. I never cared about that. But yesterday I continued working on zorroutils on the Pentium at home (using /proc/bus/zorro copied from my Amiga) and got bitten by it, too. This patch should fix the alignment problems: --- include/linux/zorro.h.orig Sat Jun 20 23:41:15 1998 +++ include/linux/zorro.h Sun Jun 21 00:04:00 1998 @@ -114,7 +114,7 @@ __u8 ln_Type; __s8 ln_Pri; /* Priority, for sorting */ __s8 *ln_Name; /* ID string, null terminated */ -}; +} __attribute__ ((packed)); struct ExpansionRom { /* -First 16 bytes of the expansion ROM */ @@ -129,7 +129,7 @@ __u8 er_Reserved0d; __u8 er_Reserved0e; __u8 er_Reserved0f; -}; +} __attribute__ ((packed)); /* er_Type board type bits */ #define ERT_TYPEMASK 0xc0 @@ -152,7 +152,7 @@ void *cd_Driver; /* pointer to node of driver */ struct ConfigDev *cd_NextCD; /* linked list of drivers to config */ __u32 cd_Unused[4]; /* for whatever the driver wants */ -}; +} __attribute__ ((packed)); #else /* __ASSEMBLY__ */ Greetings, Geert -- Geert Uytterhoeven Geert.Uytterhoeven@cs.kuleuven.ac.be Wavelets, Linux/{m68k~Amiga,PPC~CHRP} http://www.cs.kuleuven.ac.be/~geert/ Department of Computer Science -- Katholieke Universiteit Leuven -- Belgium
