This can result\nin a DNA fault while doing unlazy_fpu() in __switch_to(). This will\nend up causing a DNA fault in the context of new process thats\ngetting context switched in (as opossed to handling DNA fault in the context\nof lguest launcher/helper process).\n\nThis is wrong in both pre and post 2.6.25 kernels. In the recent\n2.6.26-rc series, this is showing up as NULL pointer dereferences or\nsleeping function called from atomic context(__switch_to()), as\nwe free and dynamically allocate the FPU context for the newly\ncreated threads. Older kernels might show some FPU corruption for processes\nrunning inside of lguest.\n\nWith the appended patch, my test system is running for more than 50 mins\nnow. So atleast some of your oops (hopefully all!) should get fixed.\nPlease give it a try. I will spend more time with this fix tomorrow.\n\nReported-by: Simon Holm Thøgersen \u003codie@cs.aau.dk\u003e\nReported-by: Patrick McHardy \u003ckaber@trash.net\u003e\nSigned-off-by: Suresh Siddha \u003csuresh.b.siddha@intel.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "a6bd8e13034dd7d60b6f14217096efa192d0adc1", "tree": "23890908b06eb8357e6ce633d35df1216f5e4213", "parents": [ "e18b094f0faa4889b06a112da17230a10b88c815" ], "author": { "name": "Rusty Russell", "email": "rusty@rustcorp.com.au", "time": "Fri Mar 28 11:05:53 2008 -0500" }, "committer": { "name": "Rusty Russell", "email": "rusty@rustcorp.com.au", "time": "Fri Mar 28 11:05:54 2008 +1100" }, "message": "lguest: comment documentation update.\n\nTook some cycles to re-read the Lguest Journey end-to-end, fix some\nrot and tighten some phrases.\n\nOnly comments change.
