Hello,
I've got reproducible kernel panics while connecting a sony cli� PDA to
a linux box using its USB cradle and pppd running on the linux box. The
computer usually crash after some time using PPP with cli� (less than 10
minutes).
Here is my setup: "noname" USB PCI card (ohci driver), SMP kernel
2.4.18.
I've got no problem with ppp when used with a modem for phone dialup.
USB works fine with other applications (pilot-link with the same sony
cli�, usb-storage and gphoto with digital cameras).
The crash occurs in usb_ohci, so i send this mail to this mailing-list
:)
Any idea?
Eric Berenguier
