-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi,
With kernel 2.6.33, plus the sector patch posted by janj...@bos.nl ~24h ago in 'possible data corruption with uml guest 2.6.32', plus the PAGE_SIZE thingy from http://marc.info/?l=user-mode-linux-devel&m=126263707311079&w=2 (as I use a static build) I get this when running the script from Matthias mentioned in the data corruption thread: attempt to access beyond end of device ubda: rw=0, want=25821990824, limit=4096000 attempt to access beyond end of device ubda: rw=0, want=26939250672, limit=4096000 attempt to access beyond end of device ubda: rw=0, want=7134666488, limit=4096000 attempt to access beyond end of device ubda: rw=0, want=25532649400, limit=4096000 attempt to access beyond end of device ubda: rw=0, want=29418829768, limit=4096000 attempt to access beyond end of device ubda: rw=0, want=20043484824, limit=4096000 attempt to access beyond end of device ubda: rw=0, want=7390279568, limit=4096000 attempt to access beyond end of device ubda: rw=0, want=26462532144, limit=4096000 [many many more] INSIDE VM: # df Filesystem 1K-blocks Used Available Use% Mounted on /dev/ubd0 2015824 1934408 60936 97% / ON HOST: - -rw-r--r-- 1 xyz xyz 2097152000 2010-03-10 17:29 /home/xyz/root_fs ...nothing wrong with that AFAICT. Also as you can see 'want' in the logs is waaay out of bounds. 2.6.32 on the other hand works fine (with the same two patches). Without the sector patch I do indeed get different md5sums (on 2.6.32): 79c29688d641a0a9ab63c7c9917619ca ./test.bin 61ea175027c3899e41620d9b15d790dd ./test.bin 62f224dec0c8313a82134da205f505b4 ./test.bin a7593a9ad0e6b374840adb715ccbda2c ./test.bin 62f224dec0c8313a82134da205f505b4 ./test.bin 62f224dec0c8313a82134da205f505b4 ./test.bin Bram. - -- Bram Matthys Software developer/IT consultant sy...@vulnscan.org PGP key: www.vulnscan.org/pubkey.asc PGP fp: 8DD4 437E 9BA8 09AA 0A8D 1811 E1C3 D65F E6ED 2AA2 -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (MingW32) iD8DBQFLl8tq46ioc5305a8RAgpZAJ99zJk3Xss/3DP/j3+XrI5T7IYPCQCfUpPm t86o2Spp8CAChE+bhe1eIzQ= =tFkr -----END PGP SIGNATURE----- ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
