Hmm, In case you have a serial cable null-modem-cable, you can use this, a terminal program (=minicom) and the kernel parameter "console=tty0 console=ttyS0,57600" to catch OOPSes... Regarding the OOPS. By now I do not understand what is going on here... there is a call to wake_up() in _drbd_process_ee. But why should a page-fault happen within this wake_up() call ??? While looking at the description of your setup, I thought that you might be the first one who tested DRBD-0.7 on a machine that actually uses HIGHMEM ? Could you try to reproduce this with HIGHMEM disabled ? -Philipp -- : Dipl-Ing Philipp Reisner Tel +43-1-8178292-50 : : LINBIT Information Technologies GmbH Fax +43-1-8178292-82 : : Schönbrunnerstr 244, 1120 Vienna, Austria http://www.linbit.com :
