Hello Keith and all It seems there is a concern around the SAL record header: SEVERITY item is defined as a 8 bits item in SAL documentation ($B.2.1 rev december 2003), but as an u16 in sal.h. This has the side effect that current code in mca.c does not call ia64_sal_clear_state_info() upon receiving corrected platform errors (priority is reported as 258 instead of 2). --- linux-2.6.12.6/include/asm-ia64/sal.h~ 2005-08-29 18:55:27.000000000 +0200 +++ linux-2.6.12.6/include/asm-ia64/sal.h 2005-12-12 10:19:17.000000000 +0100 @@ -320,7 +320,8 @@ typedef struct sal_log_record_header { u64 id; /* Unique monotonically increasing ID */ sal_log_revision_t revision; /* Major and Minor revision of header */ - u16 severity; /* Error Severity */ + u8 severity; /* Error Severity */ + u8 validation_bits; /* Validation Bits */ u32 len; /* Length of this error log in bytes */ sal_log_timestamp_t timestamp; /* Timestamp */ efi_guid_t platform_guid; /* Unique OEM Platform ID */
