Summary: dac960 driver stopped working with 2.6.22 kernel series
Product: Drivers
Version: 2.5
KernelVersion: 2.6.22 [..] 2.6.22.5
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Other
AssignedTo: drivers_other at kernel-bugs.osdl.org
ReportedBy: polynomial-c at gmx.de
Most recent kernel where this bug did not occur: 2.6.21.7 (vanilla)
Distribution: Gentoo
Hardware Environment: x86
Software Environment: Gentoo ~x86 installation
Problem Description:
Since kernel-2.6.22 my machine doesn't boot anymore from my Mylex AcceleRAID
170 (DAC960) controller.
Booting with kernel-2.6.22{,.X} I can see the following message when the kernel
tries to initialize my dac960 device:
DAC960: ***** DAC960 RAID Driver Version 2.5.48 of 14 May 2006 *****
DAC960: Copyright 1998-2001 by Leonard N. Zubkoff (lnz at dandelion.com)
DAC960#0: While configuring DAC960 PCI RAID Controller at
DAC960#0: PCI bus 0 Device 11 Function 0 I/O Address N/A PCI Address 0xD8000000
DAC960#0: DMA Mask out of range FAILED - DETACHING
DAC960#0: Unable to Enable Memory Mailbox Interface for Controller at
DAC960#0: PCI bus 0 Device 11 Function 0 I/O Address N/A PCI Address 0xD8000000
And none of the RAID-devices are found by the kernel. This is quite fatal for
me, as the root-partition of this machine is on one of the controller's
RAID-Volumes and the kernel later panics when trying to mount root-fs from a
non existant device...
I will attach lspci -v output and kernelconfig...
Steps to reproduce:
try to boot from a Mylex AcceleRAID 170 card with kernel-2.6.22 through
2.6.22.5
