(3) Set up your laptop to PXE boot using (2). This is one quick way you can test your laptop with CURRENT, without installing all the bits on the disk of your laptop. -- Craig On Wed, Mar 20, 2013 at 1:13 PM, David Wolfskill wrote: > On Wed, Mar 20, 2013 at 10:08:57PM +0200, Konstantin Belousov wrote: > > ... > > I looked at the nvidia sources to check that the driver does not use > > the interfaces which KBI was changed, and this is indeed the case, as > > expected. > > OK; thank you for checking & reporting. > > > I must admit that I have no idea why buffer cache changes could affect > > nvidia driver, and with no input on the panic (I hope that it is panic, > > and not a reset) have no idea even to speculate.
