Solaris 10 5/09 Release Notes

Panic in PCIe as dev_info Node Has No Parent Data (6517798)

The Solaris OS might panic with a null pointer dereference if the driver.conf file has been modified using the parent attribute. The following error message is displayed:

System panic: BAD TRAP: type=31 rp=2a101d31200 addr=8 mmu_fsr=0 
occurred in module "pcie" due to a NULL pointer dereference

Workaround: Before you install the Solaris 10 5/09 OS on a PCI Express (PCIe) based SPARC system, check if you have modified the driver.conf files as described below:

  1. Change to the /kernel/drv directory.

  2. Check if the parent attribute is set in the driver.conf file. If the parent attribute has been set and the last node in the parent has the word pci in it, comment out that line. Ensure that you comment out the entire property. For example:

    # name="ACME,simple" parent="/pci@7c0/pci@0/pci@9"
    # unit-address="3,1" debug-mode=12;
    name="ACME,example" parent="pseudo" instance=1;
    name="ACME,scsi" parent="/pci@7c0/pci@0/pci@9/scsi"
    unit-address="3,1" debug-mode=12;
  3. Repeat step 2 for the driver.conf files in the following directories:

    • /usr/kernel/drv

    • /platform/`uname -i`/drv

    • /platform/`uname -m`/drv

  4. Install the Solaris 10 5/09 OS.

  5. Install patch 127747-01.

  6. Change to the directories listed in steps 1 and 3. Uncomment all the lines that were commented out in step 2 in the driver.conf files.
