When loading of the AppleTalk kernel module is caused by the Netatalk daemon
starting up for the first time, the kernel reports several (usually 3
consecutively) "kmem_grow: Called nonatomically from int - size-32" error
Steps to Reproduce:
1. Stop the Netatalk daemon.
2. Remove the AppleTalk kernel module using 'rmmod'.
3. Re-insert the AppleTalk module using 'insmod'.
4. Re-start Netatalk.
# /etc/rc.d/init.d/atalk stop
Shutting down AppleTalk services: [ OK ]
# /sbin/rmmod appletalk
# /sbin/insmod appletalk
# /etc/rc.d/init.d/atalk start
Starting AppleTalk services: [ OK ]
The following is logged to /var/log/messages:
Jan 31 10:28:24 secure kernel: kmem_grow: Called nonatomically from int -
Jan 31 10:28:24 secure last message repeated 2 times
Expected Results: Well, no errors, obviously...
This on a RH 6.2 system, onto which I have retrofitted the 2.2.16-22 kernel
as distributed with RH7.0. The AppleTalk kernel module's version is "NET4:
AppleTalk 0.18 for Linux NET4.0". Tests were performed using netatalk-
1.4.99-0.20001108mdk (http://sourceforge.net/projects/netatalk/) installed
Also, the functionality of the Netatalk daemon doesn't seem to be affected
by the errors - all normal operations work as usual. Restarting Netatalk by
itself doesn't cause any errors.
With a bit of digging around on the kernel development mailing list, I found out
that this has been solved by a patch to 2.2.17pre13, thusly:
OK, let's queue that patch for analysis for future 2.2 kernel
I notice there is a new 2.2.17-14 kernel package out now:
Has this issue been fixed in this release? I could find no mention of
AppleTalk in the RPM's changelog. Or will it be resolved in a future
