Subject: 2.6.2 hangs with usb flashdisk plugged
Date: Thu, 12 Feb 2004 15:12:02 +0800 [thread overview]
Message-ID: <20040212071202.GA536@exavio.com.cn> (raw)
Hi folks,
Every time I plug my usb flashdisk (not sure what you native speakers
call it, it's a key-sized 128M usb storage device) into the system, the
kernel hangs immediately with no panic message, after spitting a few
lines like this:
hub 1-0:1.0 over-current change on port 4
hub 1-0:1.0 over-current change on port 6
hub 1-0:1.0 over-current change on port 4
hub 1-0:1.0 over-current change on port 6
It's absolutely reproduceable on 2.6.2, and here's some context info:

hub 1-0:1.0: over-current change on port 4
hub 1-0:1.0: over-current change on port 6
To this point, everything goes just fine. But, whenever I plug in my usb
flashdisk, the system completely freezes, and nothing responses but the
poweroff button.
I'm using a vanilla 2.6.2.
If additional information is needed to diagnose it, plz let me known.
