 MP3 player; can't boot with external USB 2.0 drive powered up

 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.
