I have installed martian-20061203 under linux-2.6.20. I am getting errors of the following sort: Mar 27 13:38:27 compaq kernel: VFS: Mounted root (ext2 filesystem) readonly.

In another instance, I had configured the system so that martian_dev would not be installed upon booting, but later installed it with modprobe. I didn't get the message immediately, but did get it when I disconnected my usb drive. That time the bad page state was in udev. The system has been quite stable under 2.6.20 if I don't install martian, but if I do, then I always get something like the above. Also, I've never actually run martian_modem or tried to access the modem. These errors occur just by having the module installed. Is anyone else experiencing these problems? --Paul Vojta, vojta@xxxxxxxxxxxxxxxxx
