Hi! I'm having this strange issue with a mounted USB drive. This is the device:
umass0 at uhub0 port 8 configuration 1 interface 0 "StoreJet TS512GESD400K" rev 2.10/10.00 addr 2 umass0: using SCSI over Bulk-Only scsibus2 at umass0: 2 targets, initiator 0 sd2 at scsibus2 targ 1 lun 0: <StoreJet, TS512GESD400K, 0> SCSI4 0/direct fixed serial.174c07d1B8502108567B sd2: 488386MB, 512 bytes/sector, 1000215216 sectors Accessing, reading, writing it works okay. However, when I "rapidly" (I don't how else could I phrase it) read from it, with eg. `find /mnt/usbdrive >/dev/null`, it gets stuck in a strange state so that I'm not able to umount it (only with umount -f): I always get "device is busy", but using lsof or fstat convinces me that nothing uses the filesystem/device. After `umount -f' and a remount, the filesystem doesn't seem to be corrupt, I can read back the data that I've written on it, and mount doesn't tell me that it's dirty. Is this something one of the devs would be interested in debugging (with me)? I must say that I won't be able to run -current on this machine, so I'd have to attach this to a laptop with -current, so the USB host controllers won't be the same, if this matters. dmesg: OpenBSD 5.8-stable (GENERIC.MP) #0: Tue Dec 22 01:20:44 CET 2015 root@m:/usr/src/sys/arch/amd64/compile/GENERIC.MP real mem = 17031606272 (16242MB) avail mem = 16511541248 (15746MB) mpath0 at root scsibus0 at mpath0: 256 targets mainbus0 at root bios0 at mainbus0: SMBIOS rev. 2.7 @ 0xec250 (77 entries) bios0: vendor American Megatrends Inc. version "F5" date 10/22/2014 bios0: Gigabyte Technology Co., Ltd.
