Some systems lock up without the noapic option. I found one that will freeze while trying to set up the timer interrupt. Passing 'nolapic' makes it freeze just after: Setting up timer through ExtINT... works Sometimes it will boot up and then freeze during the startup scripts. Passing the noapic option fixes all that, but it then gets 1000 spurious interrupts per second on IRQ7 (which only shows ehci using it.) Kernel version is 2.6.22. -

From: Divy Le Ray <divy@chelsio.com> Currently, the driver only tries up to 5 times (5us) to get the results of a CQ context operation.

Axel, Richard, you both reported a very similar problem to me (panic at boot on VIA c3 with 2.4.35.1 when built with gcc-4.1). I could reproduce the problem with your configs here and compare the code with your working builds. I finally tracked the problem down to a dirty trick used to prevent do_test_wp_bit() from being inlined (Axel, you identified the right file). Unfortunately, this trick does not work anymore when gcc-4.x is used without -fno-unit-at-a-time, so let's use the correct method ...

Work in progress, not for inclusion. The combination of CPU hotplug and PREEMPT_RCU has resulted in deadlocks due to the migration-based implementation of synchronize_sched() in -rt. This experimental patch maps synchronize_sched() back onto Classic RCU, eliminating the migration, thus hopefully also eliminating the deadlocks. It is not clear that this is a good long-term approach, but it will at least permit people doing CPU hotplug in -rt kernels additional wiggle room in their design and impleme...

Work in progress, not for inclusion. RCU priority boosting is needed when running a workload that might include CPU-bound user tasks running at realtime priorities with preemptible RCU. In this situation, RCU priority boosting is needed to avoid OOM. Please note that because Classic RCU does not permit RCU read-side critical sections to be preempted, there is no need to boost the priority of Classic RCU readers. Boosting the priority of a running process does not make it run any faster, at least...

It is, but the hooks are in much the same places. It could be argued that you'd embed pte notifiers in paravirt_ops for a host kernel, but that's not doable because pte notifiers use higher-level data strutures (like vmas). -- Any sufficiently difficult bug is indistinguishable from a feature. -

And lguest. I can't tell until I've actually implemented it, but I think it will seriously reduce the need for page pinning which is why only root can currently launch guests. My concern is locking: this is called with the page lock held, and I guess we have to bump the guest out if it's currently running. (Oh, and this means lguest needs to do a reverse mapping somehow, but I'll come up with something). Cheers, Rusty. -

Ulrich, For man-pages-2.66, I have added the following documentation in the open.2 man page for the new-in-2.6.23 O_CLOEXEC. O_CLOEXEC (Since Linux 2.6.23) Enable the close-on-exec flag for the new file descriptor. This is useful in multithreaded programs since using a separate fcntl(2) F_SETFD operation to set the FD_CLOEXEC flag does not suffice to avoid race conditions in multithreaded programs where one thread open...

I'm still trying to get an idea about the facts and the latest state of the incidence that violated the copyright of my code, because I just returned from vacation. I'm very disappointed about this and I hope that it was a mistake, because it is very unfair and malicious against me and the OpenBSD community.
