| StFS | Hi. First of all, sorry for cross posting from #kernel, I just realized that this might be a better fit for this channel since I believe this just started after my 14.10 upgrade. | 00:32 |
|---|---|---|
| StFS | I have an 8 physical core (two 4 core cpus) machine and I just upgraded to ubuntu 14.10. I noticed that htop is only showing activity on two cores (1 and 3 or 0 and 2 depending on where you start counting). | 00:32 |
| StFS | running 'stress -c 8' only tops these two cores... however, if I run 'stress -c 1' and then use taskset to move it to a specific core, I can in fact pick any core that I want. So they are actually there... it just seems that the scheduler never uses them unless explicitly instructed. | 00:33 |
| StFS | I'm at a bit of a loss here... does this make any sense at all? | 00:33 |
| CRCinAU | anyone familiar with the xen initrd/vmlinuz alive? | 00:39 |

| dgadomski | hello apw | 13:11 |
| apw | hi | 13:12 |
| dgadomski | apw: I have a graphic drivers/plymouth issue (#1107642), could you please take a look at this plymouth log: http://paste.ubuntu.com/8703864/ | 13:12 |
| dgadomski | apw: there are 2 vgas in this case: an integrated intel and a discrete radeon, plymouth for some reason fails to open renderer for the radeon device (card1) | 13:13 |
| dgadomski | apw: I would appreciate your help with understanding why it fails, we have a user suffering from this and he is able to provide any additional information needed | 13:15 |
| dgadomski | apw: plymouth 0.9.0 should offer the functionality of displaying bootsplash (disk encryption prompt is what is actually needed in this case) on all VGAs, but for some reason it fails to do so on the radeon device which is the only display available in this case preventing the whole system from booting | 13:17 |
| apw | dgadomski, will have a look in a bit, but does hitting ESC twice help ? | 13:22 |
| dgadomski | apw: afaik not, there is a message "unexpectedly disconnected from boot status daemon" on the only display connected, do you think it is worth retrying in this case? | 13:24 |
| apw | dgadomski, not sure i really know what that log is trying to tell me about the machine at all ... | 13:44 |
| apw | i assume the machine is bootable without splash, and when so, what does /proc/fb contain ... | 13:45 |
| apw | you likely should file a bug if you haven't and put all this info in there | 13:45 |

| StFS | Hi. I'm experiencing a _major_ regression after updating to 14.10 on my Dell Precision T5400. I've done some investigation and I've confirmed that this happens on a pristine (live cd) 14.10. Basically only 2 out of 8 cores are actually being used on my machine! A sysbench cpu test goes from ~15 seconds on 14.04 up to ~55 seconds. | 23:41 |
| StFS | does this sound familiar to anybody? | 23:41 |
| StFS | ohsix: We were talking about this yesterday... I got my proof ;) ^^ | 23:42 |
