Scenario: - Laptop Lenovo W520 (ca. 2011) - Trying to use and learn /usr/sbin/acpidb Results when executing the following commands (the three sections show the display at various stage of execution): - Initial double prompt: ------------------------------------------------------------------ [0]# acpidump -o /tmp/dsdt [0]# acpidb /tmp/dsdt Input file /tmp/dsdt, Length 0x105F6 (67062) bytes - - ------------------------------------------------------------------ - First character eaten & command ignored, second command ignored entirely, third command accepted, thereafter the prompt is missing: ------------------------------------------------------------------ [0]# acpidb /tmp/dsdt Input file /tmp/dsdt, Length 0x105F6 (67062) bytes - - Methods ETHODS: unknown command - Methods - Methods Objects of type [Method] defined in the current ACPI Namespace: \_OSI Method 0x8006ea5f0 00 Args 1 Len 0000 Aml 0x0 Found 2 objects of type [Method] in the current ACPI Namespace ------------------------------------------------------------------ - Evaluating the \OSI method crashes the program: ------------------------------------------------------------------ [0]# acpidb /tmp/dsdt Input file /tmp/dsdt, Length 0x105F6 (67062) bytes - - Methods ETHODS: unknown command - Methods - Methods Objects of type [Method] defined in the current ACPI Namespace: \_OSI Method 0x8006ea5f0 00 Args 1 Len 0000 Aml 0x0 Found 2 objects of type [Method] in the current ACPI Namespace - Evaluate \_OSI "FreeBSD" Evaluating \_OSI zsh: segmentation fault (core dumped) acpidb /tmp/dsdt [139]# \rm acpidb.core [0]# ------------------------------------------------------------------ Expected results: - The command starts with two consecutive prompts. Expected would be one. - Starting the command seems to eat the first character input. This should not happen. - The prompting is strange: The prompt appears after entering the first character. Expected is that the prompt is displayed when the debugger is ready to accept another command. - Executing the \_OSI method crashes the program. Question: - Why do I not see any other methods? - How could I execute the other methods shown in "acpidump -dt"? -- Martin
