Description Brent 2007-04-25 18:52:27 UTC
Description of problem:

I'm having trouble running Redhat Enterprise Linux 5 server on a system with an
Adaptec ASR-2010S-48MB raid controller.

I install with linux noprobe and add the i2o_block driver in order to recognize
the arrays and complete the installation.  The installation process completes

After installation, on initial boot the system hangs.  I can avoid the hangs by
disabling the readahead and readahead_later services.  If I run the readahead
processes in combination with strace by hand I witness a report of a spurious
interrupt from the i2o driver.  After the error, running processes function but
any attempt at drive IO hangs the process until the system is unusable.

Possibly related during the boot process two error messages:

PCI: Failed to allocate mem resource .... for ....
Where the devices are the:
PCI bridge:  Intel Corporation 82870P2 P64H2 Hub PCI Bridge (rev 04)
RAID bus controller: Adaptec (formerly DPT) SmartRAID V Controller (rev 01)

Version-Release number of selected component (if applicable):

How reproducible:

Every time

Steps to Reproduce:
1. Install with linux noprobe add i2o_block
2. Boot
Actual results:
Processes hang on drive io

Expected results:
A running system

This hardware has gone end-of-life, along with parallel SCSI in general. We will not be making changes to this driver in RHEL any more.
