Re: 7-Current: turn off debugging (kqread?)
yes. i got an answer on current. even though my host was not setup as a NIS client, it was trying to resolve UID/GID information. the only line in my rc.conf was NISDOMAIN= -- Kevin Kramer Sr. Systems Administrator 512.418.5725 Centaur Technology, Inc. www.centtech.com Kris Kennaway wrote the following on 07/27/07 15:12: On Tue, Jul 03, 2007 at 11:12:36AM -0500, Kevin Kramer wrote: thanks.

thanks. I rebuild this morning with this and still no change. I can't even find any info on these flags...

Re: 7-Current: turn off debugging (kqread?)
yes. that is where I have started, but I cannot get buildkernel to build
with those commented out. the UPDATING file also lists heavy debugging
turned on in userland, which I can't track down to any config files.
I've cvsup'ng now to see if I can build today.

UPDATING. But what I can't find is how to turn off debugging. I've tried
removing all debugging from the kernel, but it won't build. I can't find
any userland debugging notes to turn it off.
It is taking literally 5 minutes to login to my host and the same amount
of time to run top. Processes get stuck in kqread. Maybe this is not a
7-Current debugging problem, but I need some guidance on where to go or
what to look for.
Any help appreciated.
In your kernel config, remove these lines if they exist:
options INVARIANTS # Enable calls of extra sanity
checking
options INVARIANT_SUPPORT # Extra sanity checks of
internal structures, required by INVARIANTS
options WITNESS # Enable checks to detect
deadlocks and cycles
options WITNESS_SKIPSPIN# Don't run witness on spinlocks
for speed
You can leave the "options {K,D,G}DB" lines, they incur virtually now
performance costs.
You would get more help (possibly) if you tried posting on current@
