External drive hang (~30 seconds) when new USB drive is plugged in

Hey,

I'm having an issue where I'll be accessing a file on one of my external drives--say playing music through Rhythmbox..I'll plug in a secondary USB drive and the first drive will immediately stop responding for around 30 seconds, before "resetting" and continuing where it left off.  The secondary drive plugged in works fine the whole time.

The following is displayed in dmesg output while the problem occurs:

sr 27:0:0:1: Attached scsi CD-ROM sr1
sr 27:0:0:1: Attached scsi generic sg4 type 5
sd 27:0:0:0: [sdc] Assuming drive cache: write through
scsi 27:0:0:2: Enclosure         WD       SES Device       1032 PQ: 0 ANSI: 4
scsi 27:0:0:2: Attached scsi generic sg5 type 13
 sdc: sdc1
sd 27:0:0:0: [sdc] Assuming drive cache: write through
sd 27:0:0:0: [sdc] Attached SCSI disk
*******Here's where the 30 second hang is*******
usb 1-1: reset high speed USB device using ehci_hcd and address 2

I've tried multiple USB ports (even bought a new case) and the issue persists.

Any ideas would be greatly appreciated.

Thanks!

I believe this may have been a kernel bug, as after upgrading to kernel version 2.6.39 I do not seem to have this issue any longer.

Btw, don't buy USB controllers with VIA chipsets if you're going to use *nix...buy NEC chipset controllers.
