Was looking through boot log messages, and this one seemed 'new'...
is this saying that the device requires 66, but the driver allocated 32 bytes?
Or the opposite: i.e. driver requires 66 (according to some new standard**) but the device from 2009, has the 2009 standard of 32?
Just a WAG, but 20110413 looks like a date, that is certainly newer than the system, though it has had firmware upgrades (though none in the past 6 months or so...)...
Seems like a weird thing to be changed across drivers while not providing for some backward compat, but that's purely based on a notion that there's a driver/hw version mismatch now when before, there were no such error messages (maybe the error message is new, and it's always been broken? ;-) )...
as subj says linux-3.0.0, stock vanilla + the latest IMQ networkfilter patch. X64
[ 13.722612] ACPI Error: SMBus or IPMI write requires Buffer of length 66, found length 32 (20110413/exfield-285) [ 13.733078] ACPI Error: Method parse/execution failed [\_SB_.PMI0._GHL] (Node ffff880616962b18), AE_AML_BUFFER_LIMIT (20110413/psparse-536) [ 13.746189] ACPI Error: Method parse/execution failed [\_SB_.PMI0._PMC] (Node ffff880616962a78), AE_AML_BUFFER_LIMIT [ 13.755322] dca service started, version 1.12.1[ 13.761822] (20110413/psparse-536) [ 13.765509] ACPI Exception: AE_AML_BUFFER_LIMIT, Evaluating _PMC (20110413/power_meter-773)
Did something that would cause this? I haven't determined what the impact of the above problem is -- it might be some status progs no longer work OR maybe never worked, and now may have a clue... ? Any insights?
