Hello, one more kernel panic. We've got Intel ISP2150 chasis with two quantum atlass 36g drives, connected via SCA to mylex acceleraid 170 (firmware 6.x). Mylex logical volume was inicialized using automatic setup, cause it fully satisfied our needs (fault-tolerant mirror). It always (during successful starts and not successful ones) showed us (probe15:mly0:1:0:0): MODE SENSE(06). CDB: 1a 0 a 0 14 0 (probe15:mly0:1:0:0): ILLEGAL REQUEST asc:21,0 (probe15:mly0:1:0:0): Logical block address out of range Unsuccessful starts included: (probe6:mly0:0:6:0): INQUIRY. CDB 12 1 80 0 ff 0 (probe6:mly0:0:6:0): ILLEGAL REQUEST asc:24,0 (probe6:mly0:0:6:0): Invalid field in CDB As far as I understand, 0:6:0 is SCA processor, identified by mylex bios as: 0:06 Processor ESG-SHV SCA HBPM10 0.04 So it seams, that mylex doesn't know how to work with it. 4.2 release works without any problems, except boot message, that exists in 4.3 also: mly0 physical device 0:6 gone that is repeated several times. Kernel panics because of: Fatal trap 18: integer divide fault while in kernel mode instruction pointer: 0x8:0xc012e611 stack pointer: 0x10:0xc02256e4 frame pointer: 0x10:0xc02256fc code segment: base 0x0, limit 0xfffff, type 0x1b DPL0, pass 1, def32 1, gran 1 processor eflags: interrupt enabled, resume, IOPL-0 current process: Idle interrupt mask: 0 Stopped at mly_cam_action+0x25d: idivl 0x8c(%esi,%ebx,1),%eax trace shows: mly_cam_action xpt_action proberequestdefaultnegotiation probedone camisr swi_cambio doroti_swi any details may be given upon request. This happens both with GENERIC and tailored version of kernel. Hardware is new, stable and works with 4.2-release. Thanks for your attention ;-) Regards, Domas Mituzas DELFI Internet, UAB To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
