[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 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):

[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:

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

Does it fail to detect the device your root partition resides? -- tejun ^ permalink raw reply [flat|nested] 7+ messages in thread

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).

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 [-- Attachment #2: lspci-vvv.txt --] [-- Type: text/plain, Size: 14499 bytes --] 00:00.0

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. -- tejun [-- Attachment #2: sb600-ign-serr-internal.patch --] [-- Type: text/x-patch, Size: 2665 bytes --] diff --git a/drivers/ata/ahci.c b/drivers/ata/ahci.c index 48616c6..17c6630 100644 --- a/drivers/ata/ahci.c +++ b/drivers/ata/ahci.c @@ -82,6 +82,7 @@ enum { board_ahci_pi = 1, board_ahci_vt8251 = 2, board_ahci_ign_iferr = 3, + board_ahci_ign_interr = 4, /* global controller registers */ HOST_CAP = 0x00, /* host capabilities */ @@ -173,6 +174,7 @@ enum { AHCI_FLAG_NO_NCQ = (1 << 24), AHCI_FLAG_IGN_IRQ_IF_ERR = (1 << 25), /* ignore IRQ_IF_ERR */ AHCI_FLAG_HONOR_PI = (1 << 26), /* honor PORTS_IMPL */ + AHCI_FLAG_IGN_SERR_INTERNAL = (1 << 27), /* ignore SERR_INTERNAL */ }; struct ahci_cmd_hdr { @@ -357,6 +359,17 @@ static const struct ata_port_info ahci_port_info[] = { .udma_mask = 0x7f, /* udma0-6 ; FIXME */ .port_ops = &ahci_ops, }, + /* board_ahci_ign_interr */ + { + .sht = &ahci_sht, + .flags = ATA_FLAG_SATA | ATA_FLAG_NO_LEGACY | + ATA_FLAG_MMIO | ATA_FLAG_PIO_DMA | + ATA_FLAG_SKIP_D2H_BSY | + AHCI_FLAG_IGN_SERR_INTERNAL, + .pio_mask = 0x1f, /* pio0-4 */ + .udma_mask = 0x7f, /* udma0-6 ; FIXME */ + .port_ops = &ahci_ops, + }, }; static const struct pci_device_id ahci_pci_tbl[] = { @@ -396,8 +409,8 @@ static const struct pci_device_id ahci_pci_tbl[] = { { PCI_VDEVICE(JMICRON, 0x2366), board_ahci_ign_iferr }, /* JMB366 */ /* ATI */ - { PCI_VDEVICE(ATI, 0x4380), board_ahci }, /* ATI SB600 non-raid */ - { PCI_VDEVICE(ATI, 0x4381), board_ahci }, /* ATI SB600 raid */ + { PCI_VDEVICE(ATI, 0x4380), board_ahci_ign_interr }, /* SB600 non-raid */ + { PCI_VDEVICE(ATI, 0x4381), board_ahci_ign_interr }, /* SB600 raid */ /* VIA */ { PCI_VDEVICE(VIA, 0x3349), board_ahci_vt8251 }, /* VIA VT8251 */ @@ -462,9 +475,10 @@ static inline void __iomem *ahci_port_base (void __iomem *base, unsigned int por return (void __iomem *) ahci_port_base_ul((unsigned long)base, port); } -static u32 ahci_scr_read (struct ata_port *ap, unsigned int sc_reg_in) +static u32 ahci_scr_read(struct ata_port *ap, unsigned int sc_reg_in) { unsigned int sc_reg; + u32 serr; switch (sc_reg_in) { case SCR_STATUS: sc_reg = 0; break; @@ -475,12 +489,13 @@ static u32 ahci_scr_read (struct ata_port *ap, unsigned int sc_reg_in) return 0xffffffffU; } - return readl((void __iomem *) ap->ioaddr.scr_addr + (sc_reg * 4)); + serr = readl((void __iomem *) ap->ioaddr.scr_addr + (sc_reg * 4)); + if (ap->flags & AHCI_FLAG_IGN_SERR_INTERNAL) + serr &= ~SERR_INTERNAL; + return serr; } - -static void ahci_scr_write (struct ata_port *ap, unsigned int sc_reg_in, - u32 val) +static void ahci_scr_write(struct ata_port *ap, unsigned int sc_reg_in, u32 val) { unsigned int sc_reg; ^ permalink raw reply related [flat|nested] 7+ messages in thread
