Subject: 2.6.20 USB issue(?) [disabled by hub(EMI?)]
Date: Fri, 16 Feb 2007 09:29:57 -0500 (EST)	[thread overview]
Message-ID: <Pine.LNX.4.64.0702160928550.13505@p34.internal.lan> (raw)
In-Reply-To: <Pine.LNX.4.64.0702031903550.29127@p34.internal.lan>

This happens under heavy I/O + network traffic, it happened again, this 
time under 2.6.20-- is this normal/or would it be considered a bug? 
Because it does retry/re-discover the device.
