I have the same, or at least a very similar problem on my dapper system. The SD card is disconnected and reconnected spontaneously, with transfer rates anywhere between 0 and 4 MB/sec. This does *not* happen when running the same hardware with WinXP, where it's rock stable. So the hardware is not at fault.
I've had it with dapper beta, and still have it with the current dapper, last updated 2 days ago. I'll check on a dmesg/messages log tonight. I'm happy to perform additional tests if this is of any help (if possible without scrapping my system, it's my only one...) Ben: If you need any testing or data, you can also contact me offline, if you so desire. hth stefan -- usb flash memory hangs after copying few MB https://launchpad.net/bugs/17881 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
