Subject: Re: usb/98343: [boot] BBB reset failed errors with Creative Muvo
MP3 player; can't boot with external USB 2.0 drive powered up
Date: Tue, 13 Jan 2009 21:14:28 +0100
I tried 7.0 Release and 7.1 Release and here as well, writing to pen
drives is unreliable enough to be unusable.
How to repeat:
- Insert a pen drive formatted to UFS2 [*].
- Mount it.
- Write files. dd, cp, scp, whatever.
[*] To format the drive I had to format a disk image an dd' this out to
the drive on Linux.
What happens:
Typically after 2 or 3 MB, write operations hang. Looking at system
messages (dmsg), I get:
umass1: BBB reset failed, TIMEOUT
(null): at uhub0 port 2 (addr 2) disconnected
umass1: BBB reset failed, TIMEOUT
umass1: BBB reset failed, TIMEOUT
umass1: BBB reset failed, TIMEOUT
umass1: BBB reset failed, TIMEOUT
g_vfs_done():da1s1[WRITE(offset=65536, length=2048)]error = 5
g_vfs_done():da1s1[WRITE(offset=6144000, length=2048)]error = 5
g_vfs_done():da1s1[WRITE(offset=963479552, length=8192)]error = 5
g_vfs_done():da1s1[WRITE(offset=963487744, length=2048)]error = 5
g_vfs_done():da1s1[WRITE(offset=963489792, length=2048)]error = 5
[... repeated more often]
Additional infos:
The drive works flawlessly on several other computers, including Linux
and Mac OS X.
I'd be glad to debug this, but I need a few hints on how to do this.
My system (custom kernel):
