Blackbird/Firmware/2.00a/Release Notes

System Package 2.00 Release Notes

BMC

• No change

PNOR

• No change

FPGA

• Add standby VDDRAB 1.2V power plane controls for corresponding hardware in Blackbird planar revisions 1.02 and above.

Known Issues

• New BMC cannot IPL old PNOR and vice versa (CANTFIX)
• Lockdown of P2A bridge for security breaks AST2500 VGA passthrough -- ast driver in guest cannot read configuration due to lockdown, and qemu does not pass host device tree information with VGA configuration data to guest kernel.
• Certain DIMMs may not function in Slot 0. This is not a defect in the Blackbird planar, it is a memory VPD issue that is being worked by Raptor and the IBM memory team. Future firmware updates are expected to address this problem.
• Upgrading from a BMC that has been manually edited to add or remove users can result in loss of SSH access after the upgrade has completed. The root cause is that /etc/passwd is retained verbatim across updates if modified, and as a result the new sshd user is not present in the upgraded firmware environment.
  • Prior to upgrading such a BMC, the following line should be added to /etc/passwd on the BMC:
    sshd:x:996:995::/var/run/sshd:/bin/false
  • Alternatively, the files /etc/passwd and /etc/group can be removed immediately before reboot to apply the update. Caution should be used with this method, as failure to apply the update could then result in a requirement to use a BMC serial cable or external SPI flasher to recover.
• Systems with LSI SAS controllers (mpt3sas kernel module) crash in petitboot and are unable to boot the target OS
  • WORKAROUND: Use our current 2.01 Beta PNOR instead of the 2.00 release PNOR
