https://bugzilla.kernel.org/show_bug.cgi?id=151661 Chris "SKip" Mac-Stoker <chrismac@xxxxxxxxxx> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |chrismac@xxxxxxxxxx --- Comment #4 from Chris "SKip" Mac-Stoker <chrismac@xxxxxxxxxx> --- .. just created an account and wanted to post a confirmation of this bug, on a chassis with this controller, the "AAC: Host Adapter Dead -1" did not appear at all on an Ubuntu 14.04.1 installation (OS installed, not Live USB), but suddenly showed up after a fresh installation of 16.04 (amd64) on the same chassis and persists just like the OP says, every 10s. Otherwise the controller works normally with a RAID5 4-disk array with no noticeable performance degradation as tested with hdparm -T. Copying here the relevant lspci -vv stub in case it helps: ---(cut here)--- 02:0e.0 RAID bus controller: Adaptec AAC-RAID Subsystem: Adaptec 3805 Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV+ VGASnoop- ParErr- Stepping+ SERR+ FastB2B- DisINTx- Status: Cap+ 66MHz+ UDF- FastB2B- ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Latency: 32 (250ns min, 250ns max), Cache Line Size: 32 bytes Interrupt: pin A routed to IRQ 18 Region 0: Memory at e8000000 (64-bit, non-prefetchable) [size=2M] Capabilities: [c0] Power Management version 2 Flags: PMEClk- DSI- D1+ D2- AuxCurrent=0mA PME(D0-,D1-,D2-,D3hot-,D3cold-) Status: D0 NoSoftRst- PME-Enable- DSel=0 DScale=0 PME- Capabilities: [d0] MSI: Enable- Count=1/2 Maskable- 64bit+ Address: 0000000000000000 Data: 0000 Capabilities: [e0] PCI-X non-bridge device Command: DPERE- ERO- RBC=512 OST=4 Status: Dev=02:0e.0 64bit+ 133MHz+ SCD- USC- DC=bridge DMMRBC=1024 DMOST=4 DMCRS=16 RSCEM- 266MHz- 533MHz- Kernel driver in use: aacraid Kernel modules: aacraid -- You are receiving this mail because: You are watching the assignee of the bug. -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
