[Bug 35044] Re: speedstep-smi doesn't load anymore on thinkpad t20

[Kai Timmer]

There is a fix for this in the 2.6.16.18 Kernel:

--- a/arch/i386/kernel/cpu/cpufreq/speedstep-smi.c
+++ b/arch/i386/kernel/cpu/cpufreq/speedstep-smi.c
@@ -75,7 +75,9 @@ static int speedstep_smi_ownership (void
__asm__ __volatile__(
"out %%al, (%%dx)\n"
: "=D" (result)
- : "a" (command), "b" (function), "c" (0), "d" (smi_port), "D" (0), "S" (magic)
+ : "a" (command), "b" (function), "c" (0), "d" (smi_port),
+ "D" (0), "S" (magic)
+ : "memory"
);
dprintk("result is %x\n", result);

I merged this with the Ubuntu Kernel Sources 2.6.15-23.39 and it works.
