Red Hat Bugzilla – Bug 390531
initio driver does not recognize INI-9100UW card
Last modified: 2008-02-11 17:39:18 EST
Description of problem:
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Install Fedora 8
Under F7 kernel 2.6.21 my INI-9100UW scsi card worked fine. After upgrading to
Fedora 8, nothing is recognized and I get this in my dmesg:
ACPI: PCI Interrupt 0000:02:09.0[A] -> GSI 17 (level, low) -> IRQ 20
initio: I/O port range 0x0 is busy.
ACPI: PCI interrupt for device 0000:02:09.0 disabled
After googling, I found a post by Alan Cox saying that he missed a line in the
merging of that driver and to add it. I rebuilt the kernel with that line
added, but now my machine hard locks pretty quick during the boot up procedure.
Here is the post I found:

Looks like this is the real fix:
Hmm, just finished recompiling the kernel with the new patch and I'm still
getting the same error message. I guess that is not the right patch for my problem.
Is there any printk statements I can put in that would tell you more what is
Also, is there an easier way of building the kernel rather than applying the
patch in the spec and doing an "rpmbuild -ba --target i686 --without pae
--without smp --without xen --without debug kernel.spec"?
I want to make sure all the Fedora patches are applied before I make any changes.

plain text dmesg
Please don't post compressed files unless they're huge.
Try combining the two patches?
Custom kernel build instructions are at:
To get the fastest build:
rpmbuild -bb --target i686 --with baseonly --without debuginfo kernel.spec
Sorry about the gzip. Thanks for the baseonly flag. That sped it up tremendously.
With both patches applied my system hard locks on boot again.
Are there any more patches I can try? I've searched google over and over and
cannot find anything else related. Also, I just completely disabled SELinux
just in case that had anything to do with it and it still does not work.
Try this additional patch  on top of the other two:
Still does not appear to change anything. It did work for me in Fedora 7. It
seems like a whole lot has changed from the F7 to the F8 kernel in terms of scsi
This is being discussed on linux-kernel again...
I'll take a deeper look at this as I did the patches that broke some of them in
the first place.
I tried the latest patch and it still does not help. Just to clarify, I using
the following patches against kernel-18.104.22.168-85.fc8.src.rpm
I still get a complete lockup of my system.
Hope to have a card in a week or so to debug this
I can ship you mine if that would help any. I would just ask if you would ship
it back when you get it working. It isn't doing much for me these days ;-)
Fixed upstream (not by me). Committed to Linus tree by James Bottomley so should
be in 2.6.24 and any Fedora kernel that is 2.6.24 based once it is out.
I'll close this bug now as closed/upstream feel free to reopen it once we have a
2.6.24 kernel based package out if it still breaks.

2.6.24 patch that fixes the Initio driver
Created attachment 292861 [details]
I couldn't get it working manually patching, so I just downloaded the latest
copy of initio.c from Linus tree and stuck it in my 22.214.171.124-85.fc8 source
tree. I had to remove the line about .enable_sg_chaining, but once I did that
it compiled fine. It appears as though my tape drive is functioning now that I
loaded this driver through initrd. However, I get a weird "soft lockup" on
boot and the boot stops while it Resets the SCSI bus.
Not sure what the ramifications of that are. But it WORKS!
Fixed in 126.96.36.199-123
kernel-188.8.131.52-137.fc8 has been submitted as an update for Fedora 8
kernel-184.108.40.206-137.fc8 has been pushed to the Fedora 8 stable repository. If problems still persist, please make note of it in this bug report.
