 After this i am not getting any kernel log..
Do not understand where the problem is,so am not able to reproduce
this error again. only once i saw this problem.
 When the function mptscsih_host_reset() is called?
Is it for some hard ware failure?
 can any one pls let me know the exact reason of this fusion driver problem?
Is their any doc or site where i get some info of how fusion and SCSI
are working togather?
 I am also attaching the kernel log....
Many thanks
Debasree
