This problem is now resolved; I found a bug in the SeaLevel driver. Thanks to folks who have looked into this.

I have since upgraded to CentOS 3.4 and still no success. I had a look at the kernel code and there is a call to register_chrdrv. Could anyone tell me if that function is deprecated ?

The driver code is available from ftp://ftp1.sealevel.com/pub/SOFTWARE/SEAIO/CURRENT/

Code snippet where the driver is registering with the kernel...

// Get the major number for the actual device node assigned_major = register_chrdev(major, "SeaIO", &seaio_fops); if (assigned_major < 0) { PDEBUG(KERN_WARNING "SeaIO: can't get major %d\n", major); return assigned_major; }

            if (major == 0)
                    major = assigned_major;
            #ifdef EXPERIMENTAL_INTERRUPT_SUPPORT_ENABLED
            // get the major number for the device's FIFO
            assigned_major_buffer = register_chrdev(major - 1,

"SeaIO_FIFO", &seaio_buffer_fops); if (assigned_major_buffer < 0) { PDEBUG(KERN_WARNING "SeaIO_FIFO: can't get major %d\n", major - 1); return assigned_major_buffer; } ...

Hi all,

I am having problems to get the SeaLevel IO card to work with CentOS distro.

Basically the card is being recognised and shown by lspci BUT /proc/devices file is not updated with the new devices does anyone know why. ?

Could someone tell me what/where infos are needed to get /proc/devices to be updated.

The reason I require the /proc/devices infos is because I want to run a mknod command with those infos.

This is rather urgent so any help will be much appreciated.
