[Daniel Smolik]

Distribution: Debian Sarge
Hardware Environment: Thinkpad A21m
Software Environment: 2.6.12.1
Problem Description: When I try sleep my notebook second time kernel oops.

Steps to reproduce:
Boot kernel and press sleep button under display two times.

ksymoops 2.4.9 on i686 2.6.12.1.  Options used
      -V (default)
      -k /proc/kallsyms (specified)
      -l /proc/modules (default)
      -o /lib/modules/2.6.12.1/ (default)
      -m /boot/System.map-2.6.12.1 (default)

Warning (read_ksyms): no kernel symbols in ksyms, is /proc/kallsyms a 
valid
ksyms file?
No modules in ksyms, skipping objects
No ksyms, skipping lsmod

in 2.6.13-rc3 kernel doesn't oops., but system doesn't go to sleep. 
First time
when  I do echo 3 > /proc/acpi/sleep sytem sleeps but second time not.


I compile 2.6.13-rc3 with ACPI debuging and when I do echo 3 > 
/proc/acpi/sleep
second time system freeze an on console I see this.
