Yes. It's an ordinary SCSI disk, attached to an NCR 53c875 type controller. > ...and the two memory banks with the camera are > around 1MB and 33MB. Is that correct? Hey! Now that you say so: the internal memory bank is supposed to be 8MB, it's obviously misdetected! I never noticed that. The size of the SmartMedia card is correct though, it's a 32MB card. > Here's the interesting part. It looks just fine, until the very last line. > We try a 4K read, and it craps out on us. Here's the really wierd part: > There is supposed to be a command timeout that should have fired (from the > SCSI layer) which should have tried to unjam this -- but it didn't fire. So this means the SCSI layer is suspect? By the way: did you notice the message "unknown partition table" in the log of 2.4.15pre1? That message doesn't show up with a kernel that works. Now I seem to remember that there have been a lot of changes in de gendisk functionality recently. Those changes broke the detection of partitions. This was fixed, but could it be that these changes caused my problem? > My advice: > (1) Try the other UHCI driver > (2) Try to narrow down exactly what kernel this died in. usb-storage has > some 2.4.15-pre2 changes, but it hasn't changed for a while previous to > that. I will try the other UHCI driver first. Then I will upgrade to the latest pre-release of the kernel. If all this doesn't work out maybe I'll try some ancient kernels in order to find the patch that introduced the problem. But that takes a lot of time, which is in short supply... Does it make sense to try the latest ac-kernel first? Regards, Toon. -- /"\ | Windows XP: \ / ASCII RIBBON CAMPAIGN | "Sorry Dave...
