Probloem: I can access the tape (also a CD-RW Writer) on the SCSI bus and write = data (tar) without any errors or kernel messages to and from the tape. When I read the data back I get random changed data in the files! Repeating the procedure gives differences in different files at = different positions. The Problem occured first when changing to the = new ASUS board. With a P2B before all worked like a charm. 63359 : cmp -x usr/lib/libgmp.so /usr/lib/libgmp.so 00006ea4 00 83 00006ea5 00 c0 00006ea6 76 34 00006ea7 0c 8b 00006ea8 83 04 00006ea9 c4 b0 00006eaa f4 25 00006eab 56 00 00006eac e8 40 00006ead 77 00 00006eae bc 00 00006eaf ff 74 00006eb0 ff 0b 00006eb1 eb ff 00006eb2 0f 45 00006eb3 90 0c 00006eb5 83 55 00006eb6 b8 0c 00006eb7 01 0f 00006eb8 00 be 00006eb9 00 32 00006eba 8b eb 00006ebb 00 c8 00006ebc 83 c7 00006ebd c0 45 00006ebe 34 e8 00006ebf 8b 00 63360 : cmp -x usr/lib/libssl.so /usr/lib/libssl.so 00028864 04 77 00028865 71 70 00028868 78 80 0002886c f3 6b 00028870 79 81 00028874 dc 51 00028878 7a 82 0002887c ca 4a 63361 : cmp -x usr/lib/libm.a /usr/lib/libm.a = 0003eea4 fc 00 0003eea5 01 00 0003eea6 75 00 0003eea7 62 00 0003eea8 85 00 0003eea9 d2 00 0003eeaa 7c 00 0003eeab 06 00 0003eeac 31 00 0003eead d2 00 0003eeae eb 00 0003eeaf 5a 00 0003eeb0 89 00 0003eeb1 f6 00 0003eeb2 f7 00 0003eeb3 c2 00 0003eeb4 ff 00 0003eeb5 ff 00 0003eeb6 ff 24 0003eeb7 7f 46 0003eeb8 74 72 0003eeb9 50 65 0003eeba ba 65 0003eebb 00 42 0003eebc 00 53 0003eebd 80 44 0003eebe bf 3a 0003eebf eb 20 Checked: Changed the SCSI controller (worked well in another board) Tape and CD-Writer are o.k. at another board.
