[1.] One line summary of the problem:

SATA Problem: port is slow to respond

[2.] Full description of the problem/report:

The following messages appear while booting/in dmesg [1]: 

[...]
ata2: port is slow to respond, please be patient (Status 0x80)
ata2: port failed to respond (30 secs, Status 0x80)
ata2: softreset failed (device not ready)
ata2: softreset failed, retrying in 5 secs
ata2: port is slow to respond, please be patient (Status 0x80)
ata2: port failed to respond (30 secs, Status 0x80)
ata2: COMRESET failed (device not ready)
ata2: hardreset failed, retrying in 5 secs
ata2: port is slow to respond, please be patient (Status 0x80)
ata2: port failed to respond (30 secs, Status 0x80)
ata2: COMRESET failed (device not ready)
ata2: reset failed, giving up
scsi2 : ahci
[...]

This of course means extra long booting time :(
[1] http://wieland.homelinux.org/hp_dc5750/dmesg_2.6.19.3.txt

A further issue which -  imho is coupled w/ this one - is that my 
cd/dvd+rw (also sata) combo drive does not work: 
firstly there is no indication in dmesg that it was found and 
secondly it behaves like dead: it does not open if i press the 
button and it does not blink; it can be opened until
these message appear on the screen. I need to unplug and the replug
it after shutting down/reboot so that on the next bootup the bios 
is able to find it (else it would still behave like dead)! 
The drive itself is ok i guess (a least it works fine on a differen OS).

I found a debian bug report where the problem (but unfortunately 
not a solution that worked for me) is described:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=391867

[3.] Keywords (i.e., modules, networking, kernel):

SATA, ATA

[4.] Kernel version (from /proc/version):

Linux version 2.6.19.3 (root@kvpc31) (gcc version 4.1.2 20061115

[X.] Other notes, patches, fixes, workarounds:

Also it seems that the System is not capeable of recongnizing 
the HDD:
hdparm -i /dev/sda
HDIO_GET_IDENTITY failed: Inappropriate ioctl for device

On lkml I found similar report, but no solution:
http://lkml.org/lkml/2007/1/2/107

A user on an German mailinglist suggest to uses pata_atiixp 
instead of atiixp but yet again this does not work for me: 
http://lists.opensuse.org/archive/opensuse-mobile-de/
2007-01/msg00001.html

All the information i collection can be found at:
http://wieland.homelinux.org/hp_dc5750/

I tried several kernel version in the meantime, starting w/
the standard debian testing i386 kernel, then tried different 
vanilla versions 2.6.18.6, 2.6.19, 2.6.19.3 which are all 
affected in the same way. However 2.6.20 behaves 
differtly: there is another error message which scrolls over
the screen so fast that i'm not able to read it, the only 
thing i was able to catch that it also concerns (s)ata, looking like
'ata2.0: [...] failed [...]' 

Greetings,
Sigmund

It seems whatever device connected to that ata2 went out for lunch and
never returned.

Is it happen to be a samsung one?

Your webserver is timing out.

This will work from 2.6.21; however, "hdparm -I" works now and is the
preferred way to get ID data.

Any chance you can post dmesg from 2.6.20?  Does it fail to detect the
device your root partition resides?

Well nice, but its not supposed to do that ;).

> Is it happen to be a samsung one?

No the cd/dvd+-rw drive (GSA-H31L) seems to be LG made [1] although it
has a HP sticker on it at.

[1] http://forums.driverguide.com/showthread.php?t=22969

The HDD is a Seagate Product (ST3160812AS).

More details on the hardware can be found at:
http://wieland.homelinux.org/hp_dc5750/lshw.txt

It should be working find by now, but just to be sure I've attached the
file.

> Any chance you can post dmesg from 2.6.20? 

http://wieland.homelinux.org/hp_dc5750/dmesg_2.6.20.txt

Accidentally I discovered that if I press C-c the boot process
continues. However, I only can boot into runlevel 1 else the box would
reboot a few seconds after pressing C-c.
I also noticed that the very strange cd-drive behavior is not present in
2.6.20.

Btw.: I've add a bugreport to the bugzilla:
http://bugzilla.kernel.org/show_bug.cgi?id=8044

Cheers,
Sigmund

I'm afraid that something went wrong while patching:

BTW.: I'm just curious, what's the "purpose" of this patch, it looks to
me like it is just going to ignore the problem? Or do you think that the
hardware is faulty?

ATAPI devices use error conditions regularly to report all sorts of
things including media not present.  In some variants of ahci's, this
sets seemingly unrelated error bits - JMBs set interface error and
sb600s seem to set internal error.  These errors when interpreted
literally require device reset to recover from thus ATAPI devices never
get through device ready check.  So, the patch makes ahci driver
suppress those spurious errors.

I had the same problem with kernel 2.6.20.3 (from kernel.org) on the same
machine (HP dc5750). I applied your patch, and the cd drive now works! dmesg
shows no errors logged, and I can access the drive without any problem.

Thanks,

Rod.
