Bjorn, I complained to Supermicro and mentioned that the beta BIOS they provided to one of the customers in the Redhat Bugzilla threads did not solve the issue at all. I also included links to both Bugzilla threads as well as a link to the mail you sent back to me as snipped above which contained your excellent analysis of the problem. > I posted the attached test patch to the redhat bugzilla above, but > nobody's tested it yet. Can you try it? The patch applied, booted, ran, and solved the problem perfectly. Do you want any output or configuration files to verify anything? Let me know if there is anything I can do to help. Other than that if you think it is safe to apply this, I am in favor of adding it to the mainline or other appropriate tree. > Bjorn Thanks, Matthew Hall - To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
