[PATCH 2.6.11] ide-scsi: map sg buffers in idescsi_input/output_buffers() to kernel virtual address

2005-03-09 Thread Stuart_Hayes
This patch will map the sg buffers to kernel virtual memory space in the functions idescsi_input_buffers() and idescsi_output_buffers(). Without this patch, idescsi passes a null pointer to atapi_input_bytes() and atapi_output_bytes() when sg pages are in high memory (i686 architecture). I'm att

ide-scsi oops with ide tape drive

2005-03-08 Thread Stuart_Hayes
Hello! We're seeing a null pointer dereference with certain IDE tape drives on 2.6.11 when we use it with ide-scsi (i686 architecture). The problem is that the scatter-gather pages aren't mapped to kernel virtual address space in idescsi_output_buffers()/idescsi_input_buffers(), so, if these pag
