Subject: 2.5.40 panic in uhci-hcd
Date: 06 Oct 2002 14:03:49 +0200 [thread overview]
Message-ID: <m24rbz4vve.fsf@p4.localdomain> (raw)
Sometimes when booting 2.5.40 and my Freecom USB-IDE controller (CDRW)
is connected, the kernel panics when trying to initialize the usb
subsystem. It happens right after the RH73 boot scripts print out:
Initializing USB controller (uhci-hcd): [ OK ]
In 2.5.39, this happened every time I tried to boot, but in 2.5.40 it
seems to happen about 20% of the time.
