I'm using latest linux-mips CVS kernel (2.6.10rc3) and GCC 3.4.2 on a AMD Alchemy DBau1100 development board (mipsel/MIPS32). I wasn't able to find any other location to post bugs, so please let me know if there is a bug system or more appropriate place to post this. The kernel build dies with: CC drivers/net/au1000_eth.o drivers/net/au1000_eth.c: In function `au1000_init_module': drivers/net/au1000_eth.c:100: sorry, unimplemented: inlining failed in call to 'str2eaddr': function body not available drivers/net/au1000_eth.c:1506: sorry, unimplemented: called from here drivers/net/au1000_eth.c: At top level: drivers/net/au1000_eth.c:152: warning: 'phy_link' defined but not used make[2]: *** [drivers/net/au1000_eth.o] Error 1 make[1]: *** [drivers/net] Error 2 make: *** [drivers] Error 2 I was able to get things to build with the following patch, although I'm sure this is not the proper way to do things: $ cvs diff drivers/net/au1000_eth.c Index: drivers/net/au1000_eth.c =================================================================== RCS file: /home/cvs/linux/drivers/net/au1000_eth.c,v retrieving revision 1.39 diff -r1.39 au1000_eth.c 100c100 < extern inline void str2eaddr(unsigned char *ea, unsigned char *str); --- > extern void str2eaddr(unsigned char *ea, unsigned char *str); I'm noticing another problem now though (a kernel oops), which could be related to my little patch above. I changed the definition of str2eaddr in arch/mips/au1000/common/prom.c to also not be inline just to make sure they matched. I now get this oops which seems to appear/disappear after enabling/disabling kernel options (although I have not been able to trace it down to one particular feature). This leads me to believe it is some sort of alignment bug, which is what the exception refers to. I have yet been able to build a ksymoops that will work properly, but I'm still working on that. If any one has any tips on how I can resolve this issue I could use the help. Raw oops output (not ksymoops yet) is attached. Best regards, Josh Green
