The following reply was made to PR kern/63621; it has been noted by GNATS. From: Bjarne Wichmann Petersen <freebsd.nospam@mekanix.dk> To: bug-followup@freebsd.org, marck@rinet.ru Cc: Subject: Re: kern/63621: [usb] USB MemoryStick Reader stalls/crashes system Date: Mon, 11 Jul 2005 07:34:39 +0200 I think I'm seeing something similar on 5-STABLE. I've been playing with USB2.0 trying to get a 80 GB diskdrive working with FreeBSD with speeds higher than 1MB/s. Adding ehci device to the kernel and it almost seems to work. I can mount, umount, run fdisk, newfs, copy files etc. But then suddenly the device becomes inaccessible, and trying to access the device (running ls or something) will make the console/shell freeze and becomes unresponsive. I can continue to use the PC but it's not entirely stable. Programs will not start, or freezes/crashes at random. The PC will not shutdown until I've disconnected the usb-drive. Then after some time it gives up on syncing the disks. After reboot I've to run fsck on alle drives. This stalling/locking have happened while trying to copy many large (3+ MB) files. I've also seen it after running newfs_msdos, but after 5 min I could access the drive again. This is my usb-drive: #usbdevs -v Controller /dev/usb4: addr 1: high speed, self powered, config 1, EHCI root hub(0x0000), VIA(0x0000), rev 1.00 port 1 addr 2: high speed, power 100 mA, config 1, Mass Storage Device(0x3507), Prolific Technology Inc.(0x067b), rev 1.00 And output from dmesg: umass0: Prolific Technology Inc.
