Hello, I've been having kernel panics when I use one particular USB flash drive (LEXAR MEDIA JUMPDRIVE2, rev 2.00/1.25, addr 2) with FreeBSD 6.1-PRERELEASE (See [1] below). All I have to do to get the kernel to panic is to insert and remove the drive from the USB port 2 or 3 times (without mounting the drive. Entries in /dev do not get created. See [2] for error I get when I insert the drive and [3] for the error I get when I remove the drive.) This problem happens only if the "ehci" device is enabled in the kernel (GENERIC has it enabled by default). If I comment out the "ehci" device and use only the "uhci" device, then I get a device entry in /dev and I'm able to mount the flash drive just fine and, insert and remove as many times as I like without any problems. So I suspect that it is a problem with the "ehci" driver. Unfortunately I'm not being able to get a crash dump as the system starts dumping and then freezes. I wanted to see if there is anybody on the list who has experienced anything similar. I have 2 other newer flash drives and they seem to work fine. The system seems to panic only when I use this particular flash drive. The flash drive is empty and I'm able to mount it fine if I use only the "uhci" driver. regards, joseph [1]: FreeBSD 6.1-PRERELEASE #0: Sun Feb 12 21:39:40 CST 2006 root@knowledge:/usr/obj/usr/src/sys/GENERIC [2]: umass1: LEXAR MEDIA JUMPDRIVE2, rev 2.00/1.25, addr 2 da4 at umass-sim1 bus 1 target 0 lun 0 da4: <Generic STORAGE DEVICE 1.25> Removable Direct Access SCSI-0 device da4: 40.000MB/s transfers da4: 125MB (256000 512 byte sectors: 64H 32S/T 125C) (da4:umass-sim1:1:0:0): Synchronize cache failed, status == 0x10, scsi status == 0x0 umass1: Invalid CSW: sig 0x53555355 should be 0x53425355 [3]: umass0: at uhub0 port 5 (addr 2) disconnected (da0:umass-sim0:0:0:0): lost device (da0:umass-sim0:0:0:0): removing device entry umass0: detached umass0: LEXAR MEDIA JUMPDRIVE2, rev 2.00/1.25, addr 2 umass0: BBB reset failed, IOERROR umass0: BBB bulk-in clear stall failed, IOERROR umass0: BBB bulk-out clear stall failed, IOERROR umass0: BBB reset failed, IOERROR umass0: BBB bulk-in clear stall failed, IOERROR umass0: BBB bulk-out clear stall failed, IOERROR umass0: BBB reset failed, IOERROR umass0: BBB bulk-in clear stall failed, IOERROR umass0: BBB bulk-out clear stall failed, IOERROR umass0: BBB reset failed, IOERROR umass0: BBB bulk-in clear stall failed, IOERROR umass0: BBB bulk-out clear stall failed, IOERROR umass0: BBB reset failed, IOERROR umass0: BBB bulk-in clear stall failed, IOERROR umass0: BBB bulk-out clear stall failed, IOERROR umass0: BBB reset failed, IOERROR umass0: BBB bulk-in clear stall failed, IOERROR umass0: BBB bulk-out clear stall failed, IOERROR umass0: BBB reset failed, IOERROR umass0: BBB bulk-in clear stall failed, IOERROR umass0: BBB bulk-out clear stall failed, IOERROR umass0: BBB reset failed, IOERROR umass0: BBB bulk-in clear stall failed, IOERROR umass0: BBB bulk-out clear stall failed, IOERROR umass0: BBB reset failed, IOERROR umass0: BBB bulk-in clear stall failed, IOERROR umass0: BBB bulk-out clear stall failed, IOERROR (da0:umass-sim0:0:0:0): got CAM status 0x4 (da0:umass-sim0:0:0:0): fatal error, failed to attach to device (da0:umass-sim0:0:0:0): lost device umass0: BBB reset failed, IOERROR umass0: BBB bulk-in clear stall failed, IOERROR umass0: BBB bulk-out clear stall failed, IOERROR umass0: BBB reset failed, IOERROR umass0: BBB bulk-in clear stall failed, IOERROR umass0: BBB bulk-out clear stall failed, IOERROR umass0: BBB reset failed, IOERROR umass0: BBB bulk-in clear stall failed, IOERROR umass0: BBB bulk-out clear stall failed, IOERROR umass0: BBB reset failed, IOERROR umass0: BBB bulk-in clear stall failed, IOERROR umass0: BBB bulk-out clear stall failed, IOERROR umass0: BBB reset failed, IOERROR umass0: BBB bulk-in clear stall failed, IOERROR umass0: BBB bulk-out clear stall failed, IOERROR (da0:umass-sim0:0:0:0): removing device entry Opened disk da0 -> 5
