There used to be a symbol+0xN/0xM in the EIP: line. Are you > saying that ksymoops rubbed that out and stuck a hex number in there?
The kernel's x86 format is: printk("EIP: %04x:[<%08lx>] CPU: %d\n",0xffff & regs->xcs,regs->eip, smp_processor_id()); print_symbol("EIP is at %s\n", regs->eip); so what you have there is the first EIP: line. The "EIP is at symbol+0xN/0xM" is produced by the print_symbol statement, which ksymoops decided to omit from the output. It can be clearly seen from the rest of the oops (the call trace) that print_symbol definitely does produce output, so kallsyms hasn't been disabled. > I wonder if there's something clever we could do to the kallsymsised oops > output so that ksymoops would simply cease to recognise it. I have been wondering why we still mark the addresses with [< >] even though we've decoded them ourselves. Maybe omitting these would be sufficient in the kallsyms-decoded case? -- Russell King Linux kernel 2.6 ARM Linux - http://www.arm.linux.org.uk/ maintainer of: 2.6 Serial core - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
