Description dellaric 2003-04-19 08:01:01 UTC 
Description of problem:

procinfo -m gives 'Segmentation fault' when there are more than 32 character
devices in /proc/devices

Version-Release number of selected component (if applicable):

procinfo-18-8

How reproducible:

always, when there are more than 32 character devices in /proc/devices

Steps to Reproduce:

> procinfo -a

or

> procinfo -m
    
Actual results:

Segmantation fault

Expected results:

it should work ...

Additional info:

I suggest to increase the values of MAX_CHRDEV (and maybe MAX_BLKDEV) in
procinfo.h from the current value of 32 to (for example) 64 (or more).

Arjan, what are the kernel defined limits for this?
Comment 2 Arjan van de Ven 2003-04-19 10:48:49 UTC 
For 2.4 kernels there is a maximum of 256 character major numbers
