1. usb-storage causes system freeze on large transfers. 2. When transferring data from a SanDisk ImageMate SDDR-31 loaded with an IBM Microdrive, I get random system freezes. In the first case, using 2.4.0-test10 with a 50MB transfer, the system dropped out of X with a console freeze and a message about the watchdog timer. Sorry, but I didn't have paper around to write out the whole message. In the second and third cases, using 2.4.0-test11 with 10-20MB transfers, the system became non-responsive and required a hard reboot. No messages were given in the log files. All of the cases were within a three hour period on the same machine (see description below). In each case, the command "cp /mnt/camera/* ." was issued. Note that I have had a half-dozen successfully completed transfers of 10-40MB in between these errors. The words "race condition" come to mind. 3. Keywords: usb usb-storage 4. Kernel version: 2.4.0-test10/2.4.0-test11 5. No OOPS available. 6. "cp /mnt/camera/* ." will cause the error. In this case, I mounted /mnt/camera on /dev/sdd1, where the usb-storage driver had provided /dev/sdd1 for the SanDisk device. 7.
