Hi all, I reported this in mid January (I thought I had sent to the list but the report went to Ingo and Steven off list)
I'm seeing the same problem in 2.6.15-rt21 in some of my machines. After a reboot into the kernel I just login as root in a terminal, start the jackd sound server ("jackd -d alsa -d hw") and when stopping it (just doing a <ctrl>c) I get a bunch of messages of this form:
> Trying to fix it up, but a reboot is needed > Bad page state at __free_pages_ok (in process 'jackd', page c10012fc)
Has anyone else seen this?
I'm in the process of building an -rt21 kernel before posting more detailed error messages (this kernel is patched with some additional stuff).
Ingo had suggested at the time I enable DEBUG_PAGEALLOC and DEBUG_SLAB to get more information (Jan 21 or so), I was never able to get the machine to boot into that kernel, I kept getting oopses. Weird, I'm trying to find the post I sent to lkml (I have it in my mailbox) in the lkml archives to include a link and can't find it...
More details later... -- Fernando
