Description Neal Groothuis 2005-07-13 09:10:03 UTC

Distribution: Fedora Core 3
Hardware Environment: x86
Software Environment: 
Problem Description: The Adaptec I2O RAID driver (dpt_i2o.c) has a few character
devices with major number 151 that it uses to communicate with userspace
utilities.  These devices are not registered with sysfs, so udev can't pick them
up.  

Steps to reproduce:
1) Boot Linux on a machine with an Adaptec I2O RAID controller.  
2) Note that there's no "dev" file in class/scsi_host/hostX in sysfs.

Where did we end up on this?  Problem still present in 2.6.13-rc4?

Did you try using the other I2O drivers? 
Device Drivers->I2O Support?

Comment 2 Neal Groothuis 2005-07-29 07:56:54 UTC

I saw nothing that would indicate that this has been fixed in the 
current version of the kernel.

I have not explored using the I2O drivers; I will do so when I have a 
chance.

Mark, could you please take a look at this one, maybe create yourself a
bugzilla account and add it to your todo list?

Thanks.

Comment 4 Andrew Morton 2005-09-14 23:15:36 UTC

Is all this fixed up now?

Comment 5 Mark Salyzyn 2005-09-15 04:47:57 UTC

The applications 'assume' the dpt_i2o driver is utilizing major number 151 and 
make their own nodes when communicating with the Adapter, so I wonder why 
there is a need to register with sysfs? The driver does make calls to 
register_chrdev() which should make all the arrangements none-the-less.

Comment 6 Natalie Protasevich 2007-07-10 13:50:53 UTC

Any updates on this problem?
Thanks.

Comment 7 Neal Groothuis 2007-07-10 14:47:19 UTC

I left the position where I had access to the systems with the Adaptec SCSI cards about two months ago, but I don't believe that the problem had been fixed at that point.

Comment 8 Andrew Morton 2007-08-02 17:29:58 UTC

Mark, do you think this is still valid, or should we shut the bug down?

Thanks.

Comment 9 Alan 2008-09-22 11:52:15 UTC

Closing: dpt_i2o works as is, there seems little point in breaking it, and its not the preferred i2o driver anyway
