Subject: Bad address problem while reading from hard disk(using sys_read).
Date: Fri, 20 Jun 2003 22:40:00 -0700 (PDT)	[thread overview]
Message-ID: <20030621054000.66503.qmail@web10704.mail.yahoo.com> (raw)

Hi,
    I developed a kernel module. Within that i am
dynamically allocating memory(using kmalloc and
vmalloc) for a buffer to read data. After that while
trying to read into this buffer from the hard disk
using sys_read i am getting an error. And the same
error i am getting while writing into another buffer,
which was allocated in the same way, using sys_write.
The error number set is -14(EFAULT) i.e., Bad address.


   Give me any idea to resolve the problem.

  If anyone help me i am gretful to them.

Thanks & Regards
