Hi, I've been trying to get the aha152x driver working with an adaptec SCSI card (aic-6360 based ISA card) and mustek MFS-12000-SP scanner with partial success.
I have had the scanner working with a DTC card and the NCR driver, but as it has no interrupts, and took the systems entire attention for 30 seconds to scan, I needed to change the card. With the aha152x diver, the scanner is found & initialized and the scan commences - but about the time the first data is returned from the scanner I get a NULL pointer exception. It is happening in aha152x.c about line 1523 : (the line number is approximate, I have edited the file a bit) SCpnt->SCp.ptr = SG_ADDRESS(SCpnt->SCp.buffer); It is on the first call to internal_queue where SCpnt->use_sg is non-zero. The exception occurs because SCpnt->SCp.buffer->page is NULL This is 100% repeatable, and I added some code to return FAILED when the problem occurs - so I can run tests easily enough. I realize this is likely a SCSI driver problem, but imagine someone might have seen it before. Mike -- WA Network Maintenance I can tell a computer http://www.wanm.com.au to do anything!
