Hi!
This is wrong:
#ifdef CONFIG_X86_TSC
static int __init tsc_setup(char *str)
{
printk(KERN_WARNING "notsc: Kernel compiled with
CONFIG_X86_TSC, "
"cannot disable TSC.\n");
return 1;
}
#else

TSC is used even on machines when CONFIG_X86_TSC is not set (X86_TSC
means _require_ TSC), but it is not properly disabled when it is
unusable, because acpi code understood the config switch as "may use
TSC".
This actually fixes suspend problems on my x60.

I guess so, as nohz=off
TSC is used even on machines when CONFIG_X86_TSC is not set (X86_TSC

Hi!
I'm trying to use the "sleepy test" here, unfortunately it locks for
10-or-so seconds.
Problem is in wait_event_timeout: timeouts take about 100x as long as
they should. Code in drivers/input/serio/libps2.c:
+ printk("ps2_command waiting event: %d\n", timeout);
timeout =

When is this code called ?
from serio_suspend. It is normal device, not a sysdev, AFAICT.
nohz=off fixes that.
notsc fixes
