lamontnow we just need a working klibc, and we can go to initramfs12:04
BenCi got a WARN_ON() in free_initmem(), but it looks harmless12:05
lamontyeah - that's um, expected12:05
BenCwell, it calls smp_call_function during a point when I belive irqs aren't enabled yet, so it makes sense :)12:06

BenCjbailey: ping02:19
jbaileyBenC: pong02:22
BenCjbailey: get my email regarding ac880 for that customer?02:22
jbaileyBenC: I did, thanks.  Do they need the new kernel that you're about to upload, or do they need the next one that will go in?02:23
BenC-6.8, which will be my next upload02:23
BenCjbailey: I got to thinking that maybe, if I fix the crash in breezy, the sound will work, but the hda driver is so different between the two that I have no idea if that's a correct assumption or not02:24
jbaileyAnd I need to test a ppc64 kernel for you.02:24
=== jbailey fetches
BenCjbailey: I may do a test kernel build with the fix for 2.6.12-10, and we can let them test that in the meantime, if you'd like02:24
BenCyes, that would be nice, thanks :)02:25
jbaileyIt seems like the best thing to do is get them to test the next dapper kernel, first.02:25
jbaileyThat way we know that the problem is actually completely solved in the development branch.02:26
BenCI'm almost 100% sure that it is fixed in dapper now, but a test would be a good idea02:27

crimsunif it's alc, it should be.02:27

infinityYour G4 shows 45 bogomips?02:53
infinityThat's weird that they use a different loop for G3 and G4, since they're virtually identical.02:54
infinity(My G3 is ~2000 bogomips..)02:54
jbaileyG3's were clearly 'leeter.02:54

infinity(And who needsa altivec anyway?)02:55
infinityStill, odd.  Something to ask benh about some day, and he'll say "Like I remember why I did that", and I'll go "oh.."02:55
BenCis benh ever on linuxnet?03:14
BenCjbailey: as of right now, I only have two possible reasons for this crash...1) GCC-4 related, may need to try a gcc-3.4 compile03:16
BenCthe crash is happening in either out_8() or in_8(), which are assembly03:16
BenC2) it might be caused by the fact that breezy ppc64 was using discontiguous memory model and dapper is flatmem03:16
BenCI'm leaning toward the first03:17
BenCthe code for CMOS_READ(), where it is crashing is the same in 2.6.12 and 2.6.15, so it's not a bug from that code directly03:18
fabbioneBenC: yes he is, but not 24h03:20
infinityI'm scared to death of this switch to gcc-4.0 for the kernel, personally.03:21
BenCI had already heard that ppc64 may need gcc-3.4, so this wouldn't be a surprise03:23
BenCbut everything else should be fine, and so far I haven't seen, nor heard of any problems from it03:23
infinityI have a lovely OOPS from fglrx, but my hardware has never liked fglrx, so I'm unwilling to commit to it being the driver, kernel, or compiler's fault until I get more bug reports from this upload.03:24

BenClooks like ppc and hppa may be the only ones left still using gcc-3.403:25

jbaileyNo ccache? =)03:37
BenCcompiler switch, so it wouldn't help anyway :)03:37
jbaileyAh, dropping back to 3.4?03:38
BenCyeah, about the only thing I can think of right now that might cause this03:38
BenCit's getting some sort of sigbus trap on a byte sized read/write from IO memory...it's very odd for it to do that03:39
BenCfor all I know the trap is expected, and the trap to fix it up just isn't set :/03:39
