Bugreport: SATA Problem: port is slow to respond

Bugreport: SATA Problem: port is slow to respond

[Sigmund Scheinbar]

Hello there!

Here my first bugreport on the linux kernel:

[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 :(

A further issue which -  imho is coupled w/ this one - is that my
cd/dvd+rw (also sata) combo drive simply 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:

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

SATA, ATA

[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

A user on an German mailinglist suggest to uses pata_atiixp
instead of atiixp but yet again this does not work for me:

I've 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
differently: 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 [...]'
