https://bugzilla.kernel.org/show_bug.cgi?id=53281 Summary: megaraid_mbox kernel panic during boot Product: SCSI Drivers Version: 2.5 Kernel Version: 2.6.26, 2.6.32, 3.2 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: high Priority: P1 Component: Other AssignedTo: scsi_drivers-other@xxxxxxxxxxxxxxxxxxxx ReportedBy: romomoruno@xxxxxxxxx Regression: Yes Distribution: Debian Squeeze Kernel: 2.6.32 Tested kernel not failing: 2.6.18 (etch) Tested kernel failing: 2.6.26 (lenny), 2.6.32 (squeeze), 3.2 (squeeze-backport) It appears be a problem with megaraid_mbox kernel module during boot on linux systems with a LSI Megaraid SCSI adaptor, with three SCSI hard disks in raid 5 and a SCSI DAT Tape (non-RAID device) connected on same adaptor. I have 17 servers affected with different hardware configurations, and common point combination is a DAT device tape connected to LSI Megaraid adaptor with three hard disks array in raid 5. Disconecting SCSI DAT Tape device from LSI adaptor or connecting it on a second adaptor solved the problem, but unfortunatelly no option for me.
