I'm having some problems with large writes to two separate USB drives 
under two separate environments.

The Drives:

   Maxtor personal Storage 300LE
   Storix Compact Drive

The Systems:

   Dell Optiplex with RedHat 7.2 (kernel 2.4.9, USB 1.1)
   Custom MIPS-based system (kernel 2.4.2 and 2.4.19-rc1, USB 2.0)

The drives test fine with a Dell Dimension running Windows 2000.

While formatting the drives for ext2 on either Linux system, the 
format process hangs for 30 seconds at a time while writing the inode 
table.  If the drive is formatted, and I attempt to copy a large 
number of files to it, the copy will stall for 30-40 seconds at a 
time during the write.  The MIPS system will usually hang at some 
point, early on in the copy process.

Has anyone seen anything like this before?  If not, I'll escalate my 
email to the usb-developers list and see if I can get any input on 
how to do a little kernel hacking to track down the cause of the 
problem.

I had planned to test the 2.5.25 kernel on the MIPS system, but it 
doesn't include MIPS support for its new threading (missing 
include/asm-mips/thread_info.h).  I'd rather stick with 2.4.19 
anyway...
