#5488: [ACPI] Haiku failed to boot on Compaq brand PC with checksum warning. --------------------------+------------------------------------------------- Reporter: siarzhuk | Owner: nobody Type: bug | Status: new Priority: normal | Milestone: R1 Component: Drivers/ACPI | Version: R1/alpha1 Keywords: | Blockedby: Platform: All | Blocking: --------------------------+------------------------------------------------- Comment(by siarzhuk): Replying to [comment:2 tqh]: > Dunno if you should have ACPI and APM enabled at the same time. I might be wrong but I thought ACPI pretty much replaces APM. Probably doesn't affect the result though. I have tried r357906 with disabled "apm" and only activated "acpi" - the result is the same. But look on the mentioned warning message from different Haiku sessions: {{{ ACPI Warning: Incorrect checksum in table [ Р] - D0, should be BE (20100121/tbutils-354) }}} {{{ ACPI Warning: Incorrect checksum in table [ Р] - D0, should be 13 (20100121/tbutils-354) }}} Note, that the checksum is always D0 but awaited values are different for different Haiku sessions. And again - system boot process is stopped after this message. -- Ticket URL: <http://dev.haiku-os.org/ticket/5488#comment:3> Haiku <http://dev.haiku-os.org> Haiku - the operating system.
