Ah yes, that would do it. In fact, the correct approach is to make dBuffer dynamic, not stack-based. That is, you should use kmalloc() to allocate the buffer space. You've got another mistake in the last argument. The timeout value should be specified in milliseconds, not in jiffies. > Anyway thanks for your attention! You're welcome.
