Description

Sun SPARC Enterprise T5120/T5220 Systems with a XVR300 Graphics Card present may fail to boot from the DVD drive. The system may hang and become unresponsive and/or issue the following error message:

    HCHalted bit is set - USB Host Controller has stopped running.

Note: This will not affect the ability to boot the system from the disk or the network.

Likelihood of Occurrence

This issue can occur on the following platforms:

SPARC Platform:

Sun SPARC Enterprise T5120 Server
Sun SPARC Enterprise T5220 Server

Note: Systems are only affected by this issue if they have a XVR300 graphics card present and a keyboard and mouse connected to the rear USB port where the DVD is also connected. If a system fails to boot, the presence of an XVR300 graphics card can be determined at the OBP prompt as follows:

    ok show-devs

The list of devices output will contain a line similar to the following:

    /pc1@400/pci@0/pci@9/SUNW,XVR-300@0

Some mother boards and some revisions of system firmware appear to be unaffected by this issue.

Possible Symptoms

If the described issue occurs, the system may hang and become unresponsive and/or issue the error message:

    HCHalted bit is set - USB Host Controller has stopped running.

Workaround or Resolution

To workaround this issue, move the keyboard to the front USB port instead of on the bus that contains the DVD drive. This workaround will be the final solution to this issue.

Internal Section: Comments:

Extensive analysis has been done on this issue. All indications are that this is a hardware issue related to the bus layout that contains the DVD drive and the rear USB ports. A root cause for the problem has never been identified. The existence of the XVR300 card on the bus seems to be key. If enough additional USB items are present on the bus the boot can work.

Two additional CRs corresponding to this issue are 6827043 and 7048904.
