patch for upstream
Patch for upstream, should apply to RHEL4 unchanged.
This is too late for U1. I will add it to the list for U2. I see that this patch has not been accepted yet. I suggest that you contact the mpt fusion maintainer, Eric.Moore, and work out a patch that he will endorse on the linux-scsi list. Then James B. will include it. Created attachment 113941 [details]
current upstream patch
Per Eric Moore, April 8, this will be submitted upstream.
The patch to fix this is included in the 3.02.18 mpt fusion driver. This driver was added for RHEL 4 U2, in kernel 2.6.9-11.1. An advisory has been issued which should help the problem described in this bug report. This report is therefore being closed with a resolution of ERRATA. For more information on the solution and/or where to find the updated files, please follow the link below. You may reopen this bug report if the solution does not work for you. http://rhn.redhat.com/errata/RHSA-2005-514.html Tested for this on a HP Integrity Superdome with fusion driver: 3.02.18. Fix is confirmed |
Description of problem: Fusion MPT driver doesn't handle multiple PCI domains correctly: Linux version 2.6.9-5.EL (bhcompile.redhat.com) (gcc version 3.4.3 20041212 (Red Hat 3.4.3-9.EL4)) #1 SMP Wed Jan 5 19:23:24 EST 2005 ... Fusion MPT base driver 3.01.16 Copyright (c) 1999-2004 LSI Logic Corporation ACPI: PCI interrupt 0000:00:02.0[A] -> GSI 25 (level, low) -> IRQ 51 mptbase: Initiating ioc0 bringup ioc0: 53C1030: Capabilities={Initiator,Target} ACPI: PCI interrupt 0000:00:02.1[B] -> GSI 26 (level, low) -> IRQ 52 mptbase: Initiating ioc1 bringup ioc1: 53C1030: Capabilities={Initiator,Target} ACPI: PCI interrupt 0000:00:03.0[A] -> GSI 27 (level, low) -> IRQ 53 mptbase: Initiating ioc2 bringup ioc2: 53C1030: Capabilities={Initiator,Target} ACPI: PCI interrupt 0000:00:03.1[B] -> GSI 28 (level, low) -> IRQ 54 mptbase: Initiating ioc3 bringup ioc3: 53C1030: Capabilities={Initiator,Target} ACPI: PCI interrupt 0001:00:02.0[A] -> GSI 133 (level, low) -> IRQ 56 mptbase: Oops, already bound (ioc1 <==> ioc0)! The driver thinks the adapter at 0001:00:02.0 is the same as the one at 0000:00:02.0 because it looks at the bus number. Version-Release number of selected component (if applicable): RHEL4, Fusion MPT base driver 3.01.16 How reproducible: 100% Steps to Reproduce: 1. Install two LSI 1030 adapters in corresponding slots of different I/O chassis of HP rx7620, rx8620, or SuperDome. 2. Set firmware "acpiconfig" to "default". 3. Boot RHEL4. Actual results: Errors from Fusion MPT driver: mptbase: Oops, already bound (ioc1 <==> ioc0)! Expected results: No errors Additional info: This was actually observed in the lab on a prototype, but it *should* happen on an rx7620, rx8620, or SuperDome as well.
