Re: Call for UMA (allocator) testers.
I have the UMA patch installed on two systems here, a 500Mhz K7 system and dual PIII SMP box, both of which have WITNESS and INVARIANTS configured in the kernel. I will run them for the next few days, and report anything that looks unusual in operation :) GG. >I'd like people to test with WITNESS and INVARIANTS, although with these >options on it is somewhat slower than the original kernel.

Re: Call for UMA (allocator) testers.
I have received a few reports of panics when loading modules. If you're going to run it you may want to staticly compile in pseudofs/procfs, etc. Thanks, Jeff On Sun, 10 Mar 2002, Glenn Gombert wrote: > I have the UMA patch installed on two systems here, a 500Mhz K7 system and > dual PIII SMP box, both of which have WITNESS and INVARIANTS configured in > the kernel.

The loading problems were fixed yesterday in revisions 1.77 and 1.78 of kern_linker.c. I suspect people, who imay have had panics, need to update to the latest version of kern_linker.c. -- Steve To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message

I'll make sure this fixes the panic for me as soon as I get home. For those of you that saw the panic, can you update this file and try again?
