(sc=e40df080) 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
