Sorry for disturbing you.

I met similar problem as Stanislaw Skowronek, but for gcc 3.4.3. I created a
kernel module, when insmod, kernel reported "dangerous relocation". I traced
the bug, found unmatched R_MIPS_HI16/LO16 in module's elf file, and kernel
refused to relocate:
00015a5c  00039a05 R_MIPS_HI16       0000000c   tos_net_debug
00015a68  00000204 R_MIPS_26         00000000   .text
00015a64  00046005 R_MIPS_HI16       0006b598   arp_proxy_list
00015a6c  00046006 R_MIPS_LO16       0006b598   arp_proxy_list

My problem arised when expression on tos_net_debug could be optimized out,
it seemed like gcc optimized out the LO16, but left HI16.

The original discussion on similar problem is at

thanks very much
