Same here with

| 03:08.0 RAID bus controller: Adaptec (formerly DPT) SmartRAID V Controller (rev 01)
|         Subsystem: Adaptec (formerly DPT) ASR-2010S I2O Zero Channel

on a Dual Xeon (SMP) machine. Tested with (nearly) vanilla kernels
2.6.19.2 + 2.6.20.1 and http://ensc.de/kernel-i2o-config.txt

I've already reversed the changes from 2.6.19 for the I2O subsystem, but 
it wasn't the solution. Probably it has something to do with the DMA 
handling, because some commands go through very well, while others 
don't. I'm working on the issue and report back as soon as i find a 
solution.

Is Adaptec 2400 controlled by drivers/message/i2o? I assume so...

If so, thats's at least three people reporting breakage in 2.6.19 and later.

Is anyone able perform a git-bisect to identify the offending commit?  It
would really help.

Thanks.

Same error here. Both 2.6.19 and 2.6.20 kernels, using Adaptec 2400A RAID.

...[snip]

This is reproduced on my SMP 2.6.19 machine.  Under 2.6.18 the i2o drive is
fine; under the latest 2.6.19 kernel, it throws errors at startup as reported in
this thread.  i2o firmware version is v001.62 2002/11/06.

Fedora is getting a bunch of bug reports about the I2O block
driver not working in 2.6.19 kernels.

Everything looks like it loads OK, but no block IO can be
done, not even reading the partition table:

I2O subsystem v1.325
i2o: max drivers = 8
i2o: Checking for PCI I2O controllers...
ACPI: PCI Interrupt Link [APC4] enabled at IRQ 19
ACPI: PCI Interrupt 0000:01:07.0[A] -> Link [APC4] -> GSI 19 (level, low) -> IRQ 19
iop0: controller found (0000:01:07.0)
iop0: limit sectors per request to 128
iop0: using 64-bit DMA
iop0: PCI I2O controller at E0000000 size=1048576
iop0: Installed at IRQ 19
i2o: iop0: Activating I2O controller...

Buffer I/O error on device i2o/hda, logical block 0
 unable to read partition table
block-osm: device added (TID: 209): i2o/hda

The driver looks unchanged except for cleanups...
