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 ;-)
