id summary reporter owner description type status component version resolution keywords cc guest host 6622 VirtualBox causes tainted swap and problem with memory allocation on Ubuntu Oliver Leitner "Tested components: upgraded bios (asus p5q board) test: memory (memtest all passes, no errors) tested hdd (internal sata II, no errors) replaced network card (intel onboard against 3com officeconnect 100mbit) changed kernels and distribution versions (2.6.30, 2.6.31, 2.6.32, 2.6.33, ubuntu: karmic & lucid) added grub2 boot params: nolapic, acpi=off, ht=on, .... no luck. created new guest: (windows xp, windows 7) no luck. Allthough different running processes get tainted, it is always the same thing thats inside the traceback: vbox. the output looks like this: -------------- May 1 08:53:51 localhost kernel: [34488.451250] Xorg: page allocation failure. order:3, mode:0x4020 May 1 08:53:51 localhost kernel: [34488.451268] Pid: 1162, comm: Xorg Tainted: P 2.6.32-21-generic #32-Ubuntu May 1 08:53:51 localhost kernel: [34488.451271] Call Trace: May 1 08:53:51 localhost kernel: [34488.451274] [] __alloc_pages_slowpath+0x56e/0x580 May 1 08:53:51 localhost kernel: [34488.451289] [] __alloc_pages_nodemask+0x15e/0x1a0 May 1 08:53:51 localhost kernel: [34488.451295] [] kmalloc_large_node+0x62/0xb0 May 1 08:53:51 localhost kernel: [34488.451300] [] __kmalloc_node_track_caller+0x125/0x180 May 1 08:53:51 localhost kernel: [34488.451306] [] ?
