Sorry, I re-used the analysis from before that change went in. I now have an oops report from 2.6.23.14 on x86_64. It is oopsing there, and only on x86_64 now, because x86_64 refuses to use a non-canonical address. ct contains what appears to be ASCII data. i386 might be dereferencing some random address instead of oopsing... 0: 48 f7 45 78 80 01 00 testq $0x180,0x78(%rbp) 7: 00 8: 74 4c je 0x56 a: 48 c7 c7 e0 18 28 88 mov $0xffffffff882818e0,%rdi %rbp has a bogus (non-canonical) address. On i386 there is no such test possible so it will just dereference the address if it is mapped. %rbp contains 8 valid ASCII chars: "salcf x\" - To unsubscribe from this list: send the line "unsubscribe netfilter-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
