Linux hangs during IDE initialization at boot for 30 sec

Linux hangs during IDE initialization at boot for 30 sec

Hi,

since at least kernel 2.6.9 I'm having a problem booting linux - it hangs 
after this

Probing IDE interface ide0...
hda: HITACHI_DK23DA-30, ATA DISK drive
elevator: using anticipatory as default io scheduler
ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
Probing IDE interface ide1...
hdc: TOSHIBA DVD-ROM SD-R2212, ATAPI CD/DVD-ROM drive
ide1 at 0x170-0x177,0x376 on irq 15

After about 30 seconds everything continues fine with

hda: max request size: 128KiB

I found additional lines in the log just before the line above:

Probing IDE interface ide2...
Probing IDE interface ide3...
Probing IDE interface ide4...
Probing IDE interface ide5...

But I only have ide0 and ide1. This problem persists even with 2.6.11-rc2. For 
the last test I removed every option from the kernel that is not needed, but 
the problem stays. So I'm sure it's not because of ACPI or PNP or the like.

With 2.6.11-rc2 I get in my syslog:

This looks like bogus HW, or bogus list of IDE interfaces ...

The IDE layer waits up to 30 seconds for a device to drop it's busy bit,
which is necessary for some drives that aren't fully initialized yet.

I suspect in your case, it's reading "ff", which indicates either that
there is no hardware where the kernel tries to probe, or that there is
bogus IDE interfaces which don't properly have the D7 line pulled low so
that BUSY appears not set in absence of a drive.

I'm not sure how the list of intefaces is probed on this machine, that's
probably where the problem is.

Ben.

How can I test to see if this is the case?

Sure, make sense.

Right. How do I find the value of D7?

I've read that people have had this problem go away if they disable this 
option:

< >     generic/default IDE chipset support

If you have chipset support for your IDE controller this isn't needed, 
and I'd recommend disabling it. The "why" it made the problem go away is 
something I can't answer.

Cheers,

Okay I'll try this tonight. I'm running a stock Fedora kernel at the moment
(rawhide) so this issue might affect more people than we think.

Known, fixed

There is a patch that allows probing for ISA ide4,5,6 etc only if there
is
no PCI bus

Since you don't care about anything except ide0 & ide1, try to add
the following to the kernel's command line:
ide2=noprobe ide3=noprobe ide4=noprobe ide5=noprobe
