[ACPI] strace acpid shows weired line

[chirag <nis...@yb...>]

Hi!

When I do strace acpid, one of the lines shows as follows.

open("/proc/acpi/event", O_RDONLY)      = -1 EBUSY (Device or resource
busy)
write(2, "acpid: can\'t open /proc/acpi/event"..., 60acpid: can't
open /proc/acpi/event: Device or resource busy) = 60

Does it have anything to do that none of my button events are logged??
  
Could someone help me out why this is happening? I am using mandrake
10.1 with uname -r showing 2.6.8.1-20mdk.
