READM FPDMA QUEUED errors
2013-05-16 19:34:33 GMT
One of my servers was throwing messages to the console (dmesg) like:
ata 3.00: exception mask ... frozen
failed command: READ FPDMA QUEUED
status: { DRDY } (timeout)
These errors showed for both ata 3.00 and 1.00, which correspond to the
mirrored host drives (software, not udat).
I've seen this error only on this one (of 6) using the Asus E35M1-M Pro
motherboard. What's a little different with this host are the hard
drives. They're both WD2500JS-75 models, circa 2007 IIRC. I suspect
these older drives do not (fully) support some functionality that the
software is attempting to use.
The apparent solution was found here:
https://bugzilla.redhat.com/show_bug.cgi?id=611350
Adding the "pcie_aspm=off" kernel parameter has indeed eliminated the
messages.
I haven't the time to investigate further, but wanted to leave this
breadcrumb here for starters.
HTH.
