Something like this in the ReleaseNotes should do: SUN T2000 users should upgrade their ALOM/OBP to at least 123482-02 before upgrading to edgy. Upgrade procedures are provided by SUN at the following URL: http://sunsolve.sun.com/search/document.do?assetkey=1-21-123482-02 (NOTE: Ubuntu/Canonical takes no responsabilities on the correctness of this documentation/upgrade - make sure to read *ALL* the information and details)
Rationale: the new edgy kernel can triggers an HyperVisor bug in handling IRQs that results in a machine halt/poweroff (ERROR: HV Abort: JBI Error (22) - PowerDown) during reboots. The machine needs to be re-powered on in order to resume normal operation (including a complete POST) that might result in long service and unscheduled downtime. -- [SPARC] - Regression - Niagara does not reboot properly https://launchpad.net/bugs/62485 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
