There's a delay between the time the module gets loaded and udev notices and creates the device node. This has bit us on other devices (tape, fcp) as well. We've had some discussions with Red Hat about it, and there's supposed to be some kind of fix in RHEL 4.5 or 5.0.

Which distribution are you running? On SLES, you can add vmcp to the list = of modules that need to be in the initrd by editing /etc/sysconfig/kernel INITRD_MODULES=3D"vmcp" Mark Post ---------------------------------------------------------------------- ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 -------------------------------------------------------- This message w/attachments (message) may be privileged, confidential or proprietary, and if you are not an intended recipient, please notify the sender, do not use or share it and delete it.
