Subject: stable-3.1: iwlwifi broken with nomsi
Date: Mon, 28 Nov 2011 20:59:39 +0100 [thread overview]
Message-ID: <20111128195939.GA15362@localhost> (raw)
Hi Greg,
I believe commit 63665158282dd3b5d70 (iwlwifi: allow pci_enable_msi fail)
needs to be added to the 3.1 stable tree as the driver fails to probe
with MSI disabled since commit 084dd79172cb3 (iwlagn: move PCI related
operations from probe and remove to PCI layer) without it:
[ 2.564901] iwlagn 0000:0e:00.0: PCI INT A -> GSI 18 (level, low) ->
IRQ 18
[ 2.564962] iwlagn 0000:0e:00.0: setting latency timer to 64
[ 2.564977] iwlagn 0000:0e:00.0: pci_resource_len = 0x00002000
[ 2.567136] iwlagn 0000:0e:00.0: pci_resource_base = f8038000
[ 2.569274] iwlagn 0000:0e:00.0: HW Revision ID = 0x0
[ 2.571375] iwlagn 0000:0e:00.0: pci_enable_msi failed
[ 2.571431] iwlagn 0000:0e:00.0: PCI INT A disabled
[ 2.575598] iwlagn: probe of 0000:0e:00.0 failed with error -1
The problem was initially reported here:
https://lkml.org/lkml/2011/10/26/314
but the fix was never marked for stable.
Thanks,
Johan
