I'm not really an expert in this area but it looks like an IRQ is received and handled before all the device data structures are set up properly (a pointer which is still null is dereferenced).

The most funky is on the list of system 3 of them share almost every hardware piece same motherboard Asus CROSSHAIR V FORMULA-Z, BIOS 2101 04/17/2014 same ram TridentX - F3-2400C10D-8GTX - G.SKILL DDR3 Memory x4 same cpu AMD FX(tm)-8350 Eight-Core Processor The main differences are one has a 8805 and intel PT1000 + nvidia GeForce GTX 560 (with nvidia blob) (working) And the two failing have a 6805 + Intel 10-Gigabit X540-AT2 + Nvidia GT218 (pci-e 1x) with nouveau As the crash message really involve aacraid, That's how I deducted the 6800 is the culprit in the stack. We updated the firmware on controler to last available at pmc/adaptec And have this running actually Controllers Found: 2 ---------------------------------------------------------------------- Controller Information ---------------------------------------------------------------------- Controller Status : OK Channel Description : SAS/SATA Controller Model : Adaptec 6805 Controller World Wide Name : 50000D1104872180 Controller Alarm : Enabled Temperature : 52 C/ 125 F (Normal) Installed Memory : 512 MB Global task priority : Low Performance Mode : Default/Dynamic Host Bus Type : PCIe Host Bus Speed : 5000 MHz Host Bus Link Width : 8 bit(s)/link(s) Stayawake Period : Disabled Spinup limit internal drives : 0 Spinup limit external drives : 0 Defunct Disk Drive Count : 0 Logical Devices/Failed/Degraded : 1/0/0 NCQ Status : Enabled Statistics Data Collection Mode : Enabled -------------------------------------------------------- RAID Properties -------------------------------------------------------- Copyback : Disabled Automatic Failover : Enabled Background consistency check : Enabled Background Consistency Check Period : 30 -------------------------------------------------------- Controller Version Information -------------------------------------------------------- BIOS : 5.2-0 (19176) Firmware : 5.2-0 (19176) Driver : 1.2-0 (30200) Boot Flash : 5.2-0 (19176) SEEPROM (Load version/ Flash version) : 2/ 8 -------------------------------------------------------- Controller ZMM Information -------------------------------------------------------- Status : ZMM Optimal -- You are receiving this mail because: You are on the CC list for the bug.
