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.

I know that debugging is turned on everywhere on 7-Current and I've read 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@
