Title:
  K43SA hangs on suspend

Status in “linux” package in Ubuntu:
  Fix Released
Status in “linux” source package in Precise:
  Invalid

Bug description:
  Hi

    K43SA hangs while suspending with 
  Linux K43SA 3.2.0-23-generic #36-Ubuntu SMP Tue Apr 10 20:39:51 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

   The hdd light comes up, but system never goes into suspend and seems
  busy writing to disk.


  -----------------------------------------

  Suspending system by force works

  
  $ cat suspend.c 
  #include <unistd.h>
  #include <sys/io.h>
  #include <stdint.h>
  #include <stdio.h>

  /* PM1 Sleep types */
  #define SLP_ON       0
  #define SLP_ST_PCLK  1
  #define SLP_S3       5
  #define SLP_S5       6
  #define SLP_SOFT_OFF 7

  #define PM1a	0x0404
  //cat /proc/ioports | grep PM1a_CNT_BLK
  //    0404-0405 : ACPI PM1a_CNT_BLK

  int main(int argc, char **argv)
  {
          uint16_t val;

          if (ioperm(PM1a, 2, 1) < 0) {
                  printf("Cannot access port %d\n", PM1a);
                  exit(0);
          }
          val = inw(PM1a);
          val &= ~(7 << 10); /* Clear SLP_TYPE */
          //val |= (SLP_SOFT_OFF << 10); /* Soft power off */
          //val |= (SLP_S5 << 10); /* Soft power off */
          val |= (SLP_S3 << 10); /* Soft power off */
          val |= (1 << 13);  /* Trigger SLP_EN */
          outw(val, PM1a);
  }
  -----------------------------------------

  Using pmdebug the below o/p is seen (
  git://kernel.ubuntu.com/cking/pmdebug.git )

  [pmdebug/locatehang] $ cat log
  Looking for function that matches hash from the Magic Number from the kernel log.
    Magic: 12:64:42 maps to hash: a3d2c
    Hash matches: acpi_hw_write_pm1_control() (address: ffffffff81383f8b)
  The kernel probably wrote to the southbridge the magic to put the machine
  into suspend or hibernate and then the machine hung.  Generally this means
  that the machine did not wake up and get back to the kernel resume successfully
  which normally indicates a BIOS issue.
