Actually the interrupt handler in ide-cd got rewritten and you're still
using the
old one (cdrom_pc_intr vs cdrom_newpc_intr). Those changes went into
mainline before
the 2.6.25-rc1 so we'll be able to test the new one only when you try out
2.6.25-rc1
or wait until 2.6.25 is released in case you don't want to try hazardous
materials
such as an -rc kernel[*] :).
I have exactly the same problem. I have a two-month old PC with a
Gigabyte P35-DS4
motherboard, which has the Intel P35 chipset with ICH10 south bridge and
additional JMicron IDE/SATA controller. I have two SATA-II hard disks
and a sole
IDE device, a Pioneer DVR-115D DVD-ROM, hooked up to the JMicron IDE port.
The motherboard also has an embedded Realtek RTL8111/8168B gigabit
ethernet controller.
The motherboard/bios assigns both the JMicron IDE controller and the Realtek
controller to the same interrupt - typically '15'. There's nothing in
the bios that
allows me to move one away from the other. I can 'reserve' or block IRQs, but
that only shifts them both to another interrupt.
well the driver probes the bios for that data and assigns the irq line it gets
from it.
Similarly, no matter what I do with the Linux kernel, using boot parameters
such
as 'acpi=off', 'noapic', 'nolapic' and the like, I can never get the
kernel to use
different interrupts for these two controllers. A 'cat
/proc/interrupts' always shows
them sharing their IRQ:
# grep ide /proc/interrupts
17: 58077 4 98999 129160 IO-APIC-fasteoi ide0, eth0
With the IDE driver compiled into the kernel any access to the DVD is fine
until I start using the network. Upon any network activity I get the
'confused'
messages and more:
kernel: hda: cdrom_pc_intr: The drive appears confused (ireason =
0x01). Trying to recover by ending request.
last message repeated 3 times
kernel: ide: failed opcode was: unknown
kernel: hda: drive not ready for command
kernel: hda: status error: status=0x58 { DriveReady SeekComplete DataRequest }
KDE even kindly pops up a window telling me that someone has inserted a
(ghost)
DVD disc, would I care to play it? :-(
I know nothing of modern/PCI hardware and their interrupt magic, but it seemed
to me that the IDE driver was erroneously picking up the interrupts destined
for
the Realtek NIC and thinking they were for it. Unfortunately there seemed to
be
no way for me to separate the two or get the IDE driver its own IRQ, either
via
the PC's bios or linux kernel boot parameters.
When I saw the recent message from Hans-Peter Jansen about this exact
problem, and Boris's comment that something in interrupt land for the
CD driver had been fixed, I thought the latest version of the kernel would
rectify matters. I installed the 2.6.25-rc2 kernel from kernel.org
but the problem
is still there.
Can you please send me your whole boot log of 2.6.25-rc2? Thanks.
As a workaround I've disabled IDE entirely in my kernel build and am using
sr_mod to present the DVD as /dev/sr0.
As a result of all this I've got several novice questions relating to
this matter.
I don't know if this mailing list is an appropriate place to ask them
.. my apologies
if not. Any quick references to reference material would be appreciated.
Given all the kernel parameters to change IRQ routing and turn ACPI actions
up, down and sideways, is there any way to tell it to assign an explicit
IRQ to a device? Or have it that the IDE driver doesn't share? I thought
CONFIG_IDEPCI_SHARE_IRQ might have something to do with it, but fiddling
the value for that had no effect. It 'feels' to me that all these IRQs seem
to
be highly adjustable by the kernel, so I was hoping there'd be a way to
let the IDE driver have one to itself.
Is there any way to leave the IDE driver compiled into the kernel but tell
it to leave the DVD-ROM drive alone, so sr_mod can claim it rather than
ide-cd? I couldn't do it with my kernel, but I think Ubuntu (7.10) does
manage it. I tried various kernel boot parameters like 'hda=scsi' or
'hda=ide-scsi' but nothing seemed to work. It would be nice to be able
to use IDE hard disks while leaving the DVD-ROM to sr_mod until this
problem is resolved.
since your cdrom seems to be hda from what i've seen above, try booting with
'hda=noprobe' or maybe 'hda=none' to see which one turns the probing off for
you. See Documentation/ide.txt for details.

Oh. I thought from all the 'IRQ routing/balancing' and the like in the

Realtek driver a different IRQ than the one being used by the ide driver.
Just my crossed-fingers hope.
Can you please send me your whole boot log of 2.6.25-rc2? Thanks.
It's attached as file 'dmesg.bug.out'.
since your cdrom seems to be hda from what i've seen above, try booting with
'hda=noprobe' or maybe 'hda=none' to see which one turns the probing off for
you. See Documentation/ide.txt for details.
I tried both options, but in both cases there was no difference; the ide_cd_mod
module was still loaded and the 'confused' message still popped up.
I did four boots/tests of the 2.6.25-rc2 kernel, with and without those
boot parameters ... on all four I had the 'confused' message several times:
hda: cdrom_newpc_intr: The drive appears confused (ireason = 0x01).
Trying to recover by ending request.
but in one - the boot with hda=noprobe - I got pages of these
error messages right after:
hda: status error: status=0x58 { DriveReady SeekComplete DataRequest }
ide: failed opcode was: unknown
hda: drive not ready for command

hda: cdrom_decode_status: status=0xc0 { Busy }
ide: failed opcode was: unknown
hda: ide_intr: huh? expected NULL handler on exit
hda: ATAPI reset complete
...
and the system essentially hung. I don't know if that was due to the
'hda=noprobe' or if that extra sensitivity is seen only every now and then.

Hi,
I suffer from unreliable cdrom operations (failing DAE and burn
sessions) with the openSUSE 2.6.18.8-0.7-bigsmp kernel.
Hi,
can please you test this with a more recent kernel. Yours is almost
ancient - from Sep. 2006.
Sure, sorry. Here we go:
Feb 14 00:18:18 kernel: hde: cdrom_pc_intr: The drive appears confused
(ireason = 0x01).
Trying to recover by ending request.
Feb 14 00:27:27 kernel: hdc: cdrom_pc_intr: The drive appears confused
(ireason = 0x01).
Trying to recover by ending request.
~ uname -a
Linux xrated 2.6.24.1-35-pae #1 SMP 2008/02/12 01:00:18 UTC i686 athlon
i386 GNU/Linux
Actually the interrupt handler in ide-cd got rewritten and you're still
using the
old one (cdrom_pc_intr vs cdrom_newpc_intr). Those changes went into
mainline before
the 2.6.25-rc1 so we'll be able to test the new one only when you try out
2.6.25-rc1
or wait until 2.6.25 is released in case you don't want to try hazardous
materials
such as an -rc kernel[*] :).
Bart?
*. As a matter of fact it runs quite smoothly on my machines.
2.6.25-rc1-git1 if you are using IDE.
however it may still have this problem
if (ireason == 0) {
write = 1;
xferfunc = HWIF(drive)-atapi_output_bytes;
} else if (ireason == 2 || (ireason == 1
(blk_fs_request(rq) || blk_pc_request(rq {
we problably need to call ide_cd_check_ireason() also for REQ_TYPE_ATA_PC
requests and remove (blk_fs_request(rq) || blk_pc_request(rq) here
write = 0;
xferfunc = HWIF(drive)-atapi_input_bytes;
} else {
printk(KERN_ERR %s: %s: The drive
appears confused (ireason = 0x%02x).
Trying to recover by ending request.\n,
drive-name, __FUNCTION__, ireason);
goto end_request;
}
Bart
Hans-Peter,
i will prepare a patch against 2.6.24 for you to try later.
Hi,
i thought that backporting ide-cd to 2.6.24 would be self-contained but the
problem is that it pulls in changes made in the block layer (ll_rw_blk.c
splitup)
and if i pull those also in the patch, i can't guarantee the stability of your
system. Besides, this turns pretty fast into a chained pulling which will result
into a subset of 2.6.25-rc1 applied ontop of your 2.6.24.1 kernel so the only
alternative is to wait after 2.6.25 has been released and tackle the problem
then.

Regards/Gruß,
Boris.

Hrm, I highly depend on that system being reliable¹, thus I would prefer a diff, if feasible at all. That way, any breakage may be embanked to PATA. OTOH, I'm willing to help to get down to the issue (knowing that this is the only way to finally get rid of it). Thanks, Pete ¹) As a matter of fact, I suffered from way to many regressions in essential subsystems (kernel, X, nss_ldap) lately, not to speak from the usual calamities in peripheral areas of such complex beasts. - To unsubscribe from this list: send the line unsubscribe linux-ide in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
