We (Michael Fetterman, George Dunlap and I) have been working over the last while on a full replacement for Xen''s shadow pagetable support. This mail contains some design notes, below; a patch against xen-unstable, giving a snapshot of the current state of the new shadow code, is at http://www.cl.cam.ac.uk/~tjd21/shadow2.patch Comments on both are welcome, although the code is not

..., I am using Samba to read a file on a Windows share from Linux. Linux version is Ubuntu 9.04 (I think). Not sure about the Samba version (sorry, can't check it now); it's whatever was packaged with Ubuntu. Windows version is Windows Server 2003 SP 2. Sometimes the file contains obviously spurious data such as random bytes, and excerpts of programs or log files. I'm not sure if the spurious data which are interpolated into the file originate from the Linux side or Windows; the identifiable text comprise fragments of Python, PHP, HTML, and what appears to be a log from MS SharedView (I co...

Hi All, I am trying to run a RTOS as a guest on a OMAP5432 evm and am seeing a spurious interrupt problem when programming the virtual timer interrupts. My RTOS test case uses the A15 Virtual timer to create a timer instance. Once programmed, the virtual timer interrupt is injected into my guest's virtual CPU interface as expected and the interrupt is also forwarded to my guest. A...

From: Christian Borntraeger <borntraeger at de.ibm.com> The virtio-rng drivers checks for spurious callbacks. Since callbacks can be implemented via shared interrupts (e.g. PCI) this could lead to guest kernel oopses with lots of virtio devices.

...oduced the concept of a bogus vector, for in irqs delivered through the i8259 PIC after IO-APICs had been set up. However, if supurious PIC vectors are received, many "No irq handler for vector" log messages can be seen on the console. This patch adds to the bogus vector logic to detect spurious PIC vectors and simply ignore them. _mask_and_ack_8259A_irq() has been modified to return a boolean indicating whether the irq is real or not, and in the case of a spurious vector, the error in do_IRQ() is not printed. One complication is that now, _mask_and_ack_8259A_irq() can get called whateve...

...BX1600MI purchased in January, attached by its supplied USB cable to a Debian 10 machine. Initially using the nut packaged in Debian 10 (2.7.4-8) this was unusable as the usbhid-ups driver kept disconnecting every few seconds. I upgraded to the git HEAD of nut and communication is now stable, but spurious events come in every so often (once or twice an hour at the moment). The events are most often "low battery" and "replace battery" but also sometimes "battery detach" and then "battery re-attach". When I call a notify script that just calls upsc at the time o...

I have noticed spurious message of the form <environment: namespace:base> when developing code for the Matrix package and testing under R-devel. These messages are not present when testing under R-2.1.1 I have not reported this because I didn't know if it was caused by my code in the Matrix package or some oth...

In the situation where a partial word is tested, lets say >0, by shifting left to get the sign bit into the msb and testing llvm is inserting a spurious right shift instruction. For example this IR: ... %0 = load i64* %a.addr, align 8 %shl = shl i64 %0, 28 %cmp = icmp sgt i64 %shl, 0 ... results in ... shlq $28, %rdi sarq $28, %rdi ; <<< spurious shift testq %rdi, %rdi gcc doesnt have this problem.

I had a brief power interruption this evening which caused a spurious shutdown. The system log contains a report of "low battery" status; however, checking the battery soon after powering up again showed a fairly typical 80% charge. The UPS had, however, been beeping to indicate imminent shutdown, which is slightly suspicious. Previous power interruptions...

I noticed that R scripts produce a spurious white line after output. For example, the following shell script, #!/bin/sh R --slave --vanilla <<EOF cat("Hello\n") EOF when made executable under the name ``hello`` along the search path, behaves like this: $ hello | od -bc 0000000 110 145 154 154 157 012 012 H...

I think I have found a way to deal with the issue of the spurious message on startup of NUT. Before implementing it, I would like to see what the other developers think of this idea. My proposal is not to wait for DUMPDONE in the startup of upsd for a duration of MAXINIT seconds, but rather to send the fake "INIT" status in response to a ups.status req...

Hi: I am trying to do a spurious regression in R but I can not find the function. Anybody used it before? The problem I have is try to do a regression with several time series. An alternative is to use the GLS function to fit the linear regression with the correlation structure AR(3) for the response (or residual). I hope the resi...

We have a few win9x workstations, that have spurious login problems. They get the message: No domain server was available to validate your password you may not be able to gain access to some network resources. The passwords are definetly correct and the problem will sometimes disappear after 5 - 10 retries, but almost always after a full restar...

...irt-topic ... but I hope that someone in here can point me to a solution as well as there are many qemu-users in here as well I assume. - I run an ancient linux-VM with a 2.2.x kernel (I have to keep it up as the software in there is compiled against that ...) We get a lot of dmesg-lines like: spurious APIC interrupt on CPU#0, should never happen I think that this slows the VM down? I tried to disable APIC in the VMs config and in the VM (kernel-option) etc but without success so far. I also tried various clock-settings ... might setting another <type> in the vm.xml help? I have: <...
