When I revert my tree back to the working snapshot time ( with cvs -d anon...@anoncvs.openbsd.org:/cvs -q up -PAd -D "2010-07-07 18:25:12 MDT" ) the resulting kernel doesn't work. The only difference to the snapshot kernel is the compiler.
In the mentioned time window i386 moved to gcc4: B B B CVSROOT:B B B /cvs B B B Module name:B B B src B B B Changes by:B B B kette...@cvs.openbsd.orgb B B 2010/07/08 14:25:40 B B B Modified files: B B B B B B share/mkB B B B B B : bsd.own.mk B B B B B B lib/libcB B B B B B : shlib_version B B B Log message: B B B Switch hppa, i386 and powerpc to gcc4.B Bump libc major to handle ABI corner B B B cases fixed in gcc4. The kernel stops working at "em_init_eeprom_params+0x16:B movl 0x4(%eax),%edx" so maybe a similar fix like below needs to be done in a second place ...
