I have recently noticed an unusual side-effect of running Wine. When I first start up my system, /proc/meminfo reports MemTotal as 256892 kb. After running Wine for awhile, /proc/meminfo reports MemTotal as 32680 kb. The system performs as if it only had 32 MB of RAM. A reboot of the system resets total memory to the proper value. My question is: 1) Has anybody else encountered this? 2)

I must be missing something obvious.

The original goal of this patchset is to fix the bug reported by https://bugzilla.kernel.org/show_bug.cgi?id=53501 Now it has also been expanded to reduce common code used by memory initializion. This is the first part, which applies to v3.9-rc1. It introduces following common helper functions to simplify free_initmem() and free_initrd_mem() on different architectures:

Hi, I've installed CentOS5.2 on an INTEL Core 2 Duo (Intel(R) Core(TM)2 Duo CPU E6550 @ 2.33GHz), 4 GB RAM (MemTotal: 4072176 kB) and my system gets sevarel minutes to startup, specially on udev daemon. Once the system is UP, every command I run gets 100% CPU and every is very slowly at the point yum -y update never ends. The system installed by default this kernel 2.6.18-53.el5PAE.

Hi Rusty, It was agreed that the balloon driver should be merged through the virtio tree, so here it goes. It depends on the config_changed patch posted earlier. ----- Following patch adds the KVM balloon driver. Changes from last version: - Get rid of global variables/structure - Use page->lru to link ballooned pages - Use dev_dbg/dev_printk - Proper kthread_should_stop handling - Move

Hi All, Thought I would let those that are interested know that I had success in running 24G on an Asus P6T with 24G kit of Kingston DDR3. While I was putting this together I saw lots of forum posts asking if anyone had tried it. Well we did here at our work and all looks great including running "memtest86" overnight. I have a fluid dynamics simulation running on it with 90% memory
