Hi,
When we execute the test of tpci in RHEL6.4GA, the system will crash:
- filesystem is broken
- network is off
Some logs are as follows:
[root@RHEL6U4GA-Intel64 ltp]# ata1.00: exception Emask 0x52 SAct 0x1 SErr 0xffffffff action 0xe frozen
ata1: SError: { RecovData RecovCommon UnrecovData Persist Proto HostInt PHYInt CommWake 10B8B Display Seq TrStaTrns UnrecFIS DevExch }
ata1.00: failed command: WRITE FPDMA QUEUED

          res 40/00:18:48:eb:33/00:00:38:00:00/40 Emask 0x56 (ATA bus error)
Quoted 12 lines
ata1.00: stauts: { DRDY }

...
Could you please find out which particular test case does it? it can be done manually the following way:
insmod ltp_pci.ko
Get your ata bus and pci slot number, then write it to the file (the number is 16bit unsigned integer, the first 8 bits is a device number, the last is a bus number):
echo "number" > /sys/devices/ltp_tcpi/bus_slot

Quoted 7 lines

Then try test-cases one by one:
echo 1 > /sys/devices/ltp_tcpi/tcase
...
echo 17 > /sys/devices/ltp_tcpi/tcase
You can check the result of each test case by reading /sys/devices/ltp_tcpi/result file. 0 - PASS, 1 - FAIL.

PCI_RESOURCES, will cause kernel crash, could you please check it?

Thanks,
Wanlong Gao

PCI_RESOURCES, will cause kernel crash, could you please check it?

And PCI_EXP_CAP_CONFIG always FAIL here on RHEL or Fedora, the log is like:

[ 4668.373058] ltp_tpci: incorrect val read. PCIE driver/device not installed: '335609857'

Could you please investigate this?
