Thought I'd give my input. I have a five year old laptop with intel graphics. On Monday October 5th (...to be fair I believe it was this Monday) I made the brave move to upgrade from 9.04 to 9.10 beta. Things worked fine. It was after one of the later updates from the default repositories when I started experiencing the 100% CPU load issue described here. I also noticed when before the said update the text size of the log messages during boot were fairly small then after the update the text was much bigger. In case this is relevant at all.

Re: [Ubuntu-x-swat] [Bug 439138] Re: [karmic] Xorg 100% CPU utilization -- only after first login
It has *nothing* to do with tcflush(). As I said above, If I revert the patch that introduced the tcflush() call, I can still reproduce this problem. This is just the semantics of select(): If a fd is in an error state, then a subsequent read() or write() won't block (since they will just return an error), so select() returns right away. So what we need to figure out is why the console fd dies. On Tue, Oct 6, 2009 at 2:26 PM, Scott James Remnant sc...@canonical.comwrote: Still nothing to do with Upstart. I would like to know *what* X is doing with that tcflush() and why it is apparently unable to cope with it returning an error. What is that trying to access, why isn't there a graceful fallback for it not existing, etc. Let's figure this out, rather than just trying to work around it. Our whole fast boot plans are contingent on getting X up early - right now you're saying that's impossible - and I want you to prove that. I'm not saying this is impossible, but clearly there's something we need to wait for before we can start X (and not for a very long time, since we don't seem to see this problem on slower systems at all). -- [karmic] Xorg 100% CPU utilization -- only after first login https://bugs.launchpad.net/bugs/439138 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in ubuntu. ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

You're right, I actually forgot to install the package, so you don't have 100% CPU anymore after reverting the commit. But this really doesn't fix the underlying problem, we still have an invalid console fd floating around, which for example is preventing us from switching virtual terminals.

Mmm, ok, this can only happen when the ioctl handler is hung_up_tty_ioctl, i.e. the tty got hung up after Xorg opened it, most probably because with the parallel start in upstart the console may get tinkered with after Xorg gets started.

[Ubuntu-x-swat] [Bug 439138] Re: [karmic] Xorg 100% CPU utilization -- only after first login
In general, xorg 100% cpu bugs are rarely actually X bugs. X is a server process that serves client requests. Client applications can send X an endless series of requests, and this will drive the X cpu utilization through the roof, but it is the client application which is bugged; the X server is just doing its job. I don't know if that is the case here, as insufficient information has been gathered so far, but the circumstantial evidence points this way. People are reporting the same issue on a wide variety of different video drivers (the difference between -nvidia and -intel is HUGE; it's quite unusual for a particular X bug to affect both.) The original report says that both the 1.6 server in Karmic and the 1.7 server upstream were tested and saw the same behavior, and that rules out a lot of possibilities of it being an X bug. The behavior that logging out and logging back in also sounds suspicious. Marc's last comment regarding the acpid socket being unavailable also sounds like a strong clue (X doesn't manage acpi stuff anymore, but acpi includes keyboard handling stuff, so I could imagine a broken acpi daemon could get stuck in a loop querying X a lot.) Anyway, for the case that it is a client application causing the problem, the troubleshooting process is straightforward: Just start killing user processes until the X CPU drops, and when that happens you have your culprit. Or, if you find that no process killing reduces the X CPU, the next step would be to use gdb and strace to get an idea on what section of X code is being triggered here. Another approach would be to bisect the problem by booting earlier versions of Karmic to find one where the problem did *not* occur, and then identify the one where it first started occurring, and then look at all the packages that changed between those two points. -- [karmic] Xorg 100% CPU utilization -- only after first login https://bugs.launchpad.net/bugs/439138 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in ubuntu. ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

Thomas emailed me off-bug with some additional insights: I'd like to bring your attention to bug #439138 [1], which I think affects a large group of people and is important to get fixed before the final release. The issue seems to be that on fast systems (for example systems with an SSD in it), X is started too early during the boot precess and this somehow results in the tty fd being in an error state, which causes select() to return immediately, but there's no code in X to recover from the error, leading to 100% CPU utilization.

[Ubuntu-x-swat] [Bug 439138] Re: [karmic] Xorg 100% CPU utilization -- only after first login
The behavior of VT switching points toward a low-level bug, rather than an application bug (cf. #437607): 0. After first login: X consumes 100% CPU 1. Alt+SysRQ+R (release KB, the VT switching seems to be disabled in default configuration?) 2. Alt+F1 (switch to VT1) 3. Something (Xorg?) causes the VT to switch immediately back to VT7 3b. The Switch user functionality in Gnome doesn't work either: VT switches always back to VT7 4. Log out from X, log then back in 5. X cpu consumption low 6. Alt+F1 7. Now the VT does not switch immediately back 7b. Also Switch user functionality works again. It could be useful if the past/future me-tooers verified if they see this same behavior vs. VT switching. There may be multiple causes for 100% cpu consumption, but to me the above seems too much of a coincidence to be accidental. -- [karmic] Xorg 100% CPU utilization -- only after first login https://bugs.launchpad.net/bugs/439138 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in ubuntu. ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
[Ubuntu-x-swat] [Bug 439138] Re: [karmic] Xorg 100% CPU utilization -- only after first login
The problem appears to be localized to the new upstart boot stuff. X is
trying to call tcflush() to flush the console of any unwritten output,
but is getting an EIO error now. Since the console doesn't get flushed,
that's leaving stuff there and makes the console fd appear to still be
readable all the time, so X never gets a chance to sleep. Since it's
never sleeping, the CPU goes to 100%.
jcristau found the EIO error is being returned at this point in
tcflush():
if (is_current_pgrp_orphaned()) {
ret = -EIO;
goto out;
}
So next question is, why is is_current_pgrp_orphaned() failing?
