Hi,

If it still get the same error, that we can conclude it as a hardware
issue.

I installed WinXP SP3 as a dual boot option onto my HP NX6325.
I booted into windows and my dual port express card was found immediately,
I
installed the latest driver from J Micron and everything seemed to be OK.
I looked through the winxp system messages and all was OK, I looked
through
device manager and it said everything was OK, all resources were OK.
I attached an external esata drive and it was detected instantly and was
available in my list of drives, I copied some files over, all went OK, I
ran
scandisk to check the drive and all went OK, the drive did not seem to
re-attach itself or give any errors. So it seems to work fine in windows.
All right; looks like the hardware works.
I then shut down my laptop and removed the esata drive and booted into
Debian
wheezy, same error appeared during boot (without any drive attached)
irq_stat 0x00000040, connection status changed
ata1: SError: { PHYInt CommWake DevExch }
ata1: hard resetting link
ata1: COMRESET failed (errno=-32)
ata1: reset failed (errno=-32), retrying in 8 secs
ata1: limiting SATA link speed to 1.5 Gbps
ata1: hard resetting link
ata1: SATA link down (SStatus 0 SControl 310)
ata1: EH complete
etc, etc.
Right.
I booted back to windows and all was OK, but, here is what I have found,
if I
boot into Linux from windows without shutting down (warm boot) then the
express card is initialised in Debian without problems and works as
normal, if
I shut down and cold boot straight to Debian, the error appears again.
Interesting. So it sounds like Windows is doing some initialization
that Linux does not.
Perhaps the card is faulty or (I suspect) there is a problem with the bios
on
the NX6325, the latest bios is dated 2007 and HP seem to have stopped
supporting this model, even though mine was purchased new in 2007.
Please send "acpidump" output as an attachment for reference.
Anyway, because the express card is so cheap I have just ordered a
replacement
of the same type, so this will tell me if it's the card that is at fault.
Ok. Thanks for your work.
linux-ide folks: any ideas for debugging this further? For example,
is there a way to find the difference between the state after a cold
boot and a warm boot from windows?
Ciao,
Jonathan
