Product: ACPI Reporter: Atanas Zhelev (zmeyski)
Component: OtherAssignee: acpi_other
Status: CLOSED DUPLICATE    
Severity: normal CC: jdelvare

Description Atanas Zhelev 2009-01-26 02:29:21 UTC 
Latest working kernel version: unknown
Earliest failing kernel version: 2.6.28
Distribution: ArchLinux x86_64, self compiled kernel from ftp.kernel.org
Hardware Environment: dell stdio 1537


Problem Description:
dmesg reports I/O resource conflict
i801_smbus 0000:00:1f.3: PCI INT C -> GSI 19 (level, low) -> IRQ 19                                              
ACPI: I/O resource 0000:00:1f.3 [0x1c00-0x1c1f] conflicts with ACPI region SMBI [0x1c00-0x1c0f]                  
ACPI: Device needs an ACPI driver

blacklisting the i2c_i801 module gets rid of the message

There is a similar bug report but the eror message is a bit different
http://bugzilla.kernel.org/show_bug.cgi?id=12376

and another one, exactly the same, in red hat bugzilla
https://bugzilla.redhat.com/show_bug.cgi?id=470479


Steps to reproduce:
boot, check dmesg
