the error,
s3: HIGH Kernel message: [ 457.594493] ACPI Error: Field [DRQL] at 144
exceeds Buffer [NULL] size 128 (bits) (20131115/dsopcode-236)

(20131115/psparse-536)
is from buggy firmware, it occured on other Dell's machines. Don't have
acpidump on this machine, so past on the analysis on that machine.
When s3 resume, will set the resource, first call the _CSR of the UAR1 device
to check the current resource, then set the resoure via _SRS,
the UART1 _CRS call SIO1.DCRS, then return CRS1 -> buffer size 128 (bits), but
_SRS call SIO1.DSRS -> but operate with the buffer size 144(bits)
CreateByteField (Arg0, 0x11, DRQL)
CreateByteField (Arg0, 0x14, DMAC)
so the error is from, the current resource tell kernel using 128bits, but the
set resource operate 144bits.
see the ACPI table,
the _CSR->DCSR always return CRS1,
Method (DCRS, 2, NotSerialized)
{
If (LEqual (Arg0, Zero))
{
ENFG (0x0C)
Store (CR6A, Local0)
Store (Local0, IOLO)
Store (CR6B, Local0)
Store (Local0, IOHI)
Store (IOLO, IORL)
Store (IOHI, IORH)
Store (0x08, LNA1)
Store (GIRQ (Arg0), IRQL)
EXFG ()
Return (CRS1)
}
Return (CRS1)
}
but the _SRS, parse/execution the resoure exceeds the CSR1 buffer,
Method (DSRS, 2, NotSerialized)
{
CreateByteField (Arg0, 0x02, IOLO)
CreateByteField (Arg0, 0x03, IOHI)
CreateWordField (Arg0, 0x09, IRQL)
CreateByteField (Arg0, 0x11, DRQL)
CreateByteField (Arg0, 0x14, DMAC)
If (LEqual (Arg1, Zero))
{
ENFG (0x0C)
STIO (0x6A, IOLO, IOHI, Zero)
SIRQ (Arg1, IRQL)
EXFG ()
DCNT (Arg1, One)
}
}
The errors above seem to cause from a buggy firmware, and need to be checked.
It might impact the UART devices, but driver might take care the UART functions.
These failures should not impact the S3 function.

Title:
[Dell OptiPlex 3011] Sometimes system won't be able to run suspend
stress test
Status in HWE Next Project:
New
Status in “linux” package in Ubuntu:
Confirmed
Bug description:
CID: 201302-12682 Dell OptiPlex 3011
Sometimes this system cannot be suspended for multiple times with
sudo fwts -P s3 --s3-multiple=5 --s3-device-check --s3-device-check-delay 45
(The first suspend cycle probably would success)
Error could be found in the log file:
S3 cycle 1 of 5
pm-suspend returned 128 after 20 seconds.
FAILED [MEDIUM] ShortSuspend: Test 1, Unexpected: S3 slept for 20 seconds,
less
than the expected 30 seconds.
FAILED [HIGH] PMActionPowerStateS3: Test 1, pm-action tried to put the machine
in the requested power state but failed.
When this happened, even suspend with the system menu would fail.
I do have it successfully suspend for 5 times once.
Steps:
1. Install 14.04, boot to desktop
2. Try to suspend this system for multiple times with the command above
3. Reboot and re-test it.
