I have experience with this basic scenario happening on several different machines.... my best guess as the the conditions that cause it are seperate simultaneous processes that generate significant i/o to the usb drive. In my case it was happening whenever updatedb/locate and a a nightly tar cf backup script were contending for the drive- once I disable the updatedb/locate crontab process the occurances of this problem dramatically reduced. The condition still does occur occasionally (say, once ever couple of months) though and I haven't been able to further diagnose it.Hello, I've got this external USB2 hard-drive. It is formatted to reiserfs.
Now, this has happened many times now, on both 2.4 and 2.6 kernels: Suddenly
the hard-drive is not responding from my computer. This happens without me
doing anything with it. Every process trying to access it hangs and it's impossible to kill those processes or umount the hard-drive properly (umount
-f works partly) because the drive is busy. I got a message in all terminals
saying "kernel: journal-601, buffer write failed". Reiserfs panics when it cannot access the drive.
There's also some bad-looking errors in /var/log/messages. The first line says: SCSI disk error : host 1 channel 0 id 0 lun 0 return code = 8000000 and another line says kernel BUG at prints.c:341! and then follows a stack trace... I've turned on reiserfs and usb debugging, so that it might help resolving the problem. I'll put the logs online if anyone could help me please..?
The hard-drive is pretty new (about a month since I bought it). I tried to reboot the computer without shutting down the external hard-drive and the drive mounts perfectly, so it seems it's something in my system or other hardware causing the problem... perhaps the USB2.0 controller?
Can anyone help me out here?
I have provided some logs which I've put online: http://farsite/pub/usbdiskprob/logs.txt Also, the full logs can be found here: http://farsite/pub/usbdiskprob/
I am not in the linux-usb-users mailing lists, so it would be nice if you could CC any replies to this message to me ([EMAIL PROTECTED])
