Still have this with 2.2.12 on: Linux pacifica 2.2.12-knfs #1 Tue Aug 31 12:59:08 PDT 1999 i686 unknown (vanilla 2.2.12 + HJL's knfs patches).
This box is hit by quite heavy NFS traffic. There seem to be no file corruption (so far).
This is the error patterns (slightly reformatted): Sep 1 22:22:54: attempt to access beyond end of device Sep 1 22:22:54: 08:08: rw=0, want=1145390407, limit=16208895 Sep 1 22:22:54: dev 08:08 blksize=1024 blocknr=1145390406 sector=-2004186484 size=1024 count=1 Sep 1 22:22:54: attempt to access beyond end of device Sep 1 22:22:54: 08:08: rw=0, want=1145390407, limit=16208895 Sep 1 22:22:54: dev 08:08 blksize=1024 blocknr=1145390406 sector=-2004186484 size=1024 count=1 Sep 1 22:22:54: attempt to access beyond end of device Sep 1 22:22:54: 08:08: rw=0, want=1145390407, limit=16208895 Sep 1 22:22:54: dev 08:08 blksize=1024 blocknr=1145390406 sector=-2004186484 size=1024 count=1 Sep 2 00:08:41: attempt to access beyond end of device Sep 2 00:08:41: 08:08: rw=0, want=285216913, limit=16208895 Sep 2 00:08:41: dev 08:08 blksize=1024 blocknr=285216912 sector=570433824 size=1024 count=1 Sep 2 00:08:41: attempt to access beyond end of device Sep 2 00:08:41: 08:08: rw=0, want=285216913, limit=16208895 Sep 2 00:08:41: dev 08:08 blksize=1024 blocknr=285216912 sector=570433824 size=1024 count=1 Sep 2 20:59:22: attempt to access beyond end of device Sep 2 20:59:22: 08:08: rw=0, want=1668444976, limit=16208895 Sep 2 20:59:22: dev 08:08 blksize=1024 blocknr=1668444975 sector=-958077346 size=1024 count=1 Sep 2 20:59:22: attempt to access beyond end of device Sep 2 20:59:22: 08:08: rw=0, want=1668444976, limit=16208895 Sep 2 20:59:22: dev 08:08 blksize=1024 blocknr=1668444975 sector=-958077346 size=1024 count=1 Sep 2 20:59:22: attempt to access beyond end of device Sep 2 20:59:22: 08:08: rw=0, want=1668444976, limit=16208895 Sep 2 20:59:22: dev 08:08 blksize=1024 blocknr=1668444975 sector=-958077346 size=1024 count=1 Sep 2 20:59:33: attempt to access beyond end of device Sep 2 20:59:33: 08:08: rw=0, want=1668444976, limit=16208895 Sep 2 20:59:33: dev 08:08 blksize=1024 blocknr=1668444975 sector=-958077346 size=1024 count=1 Sep 2 20:59:33: attempt to access beyond end of device Sep 2 20:59:33: 08:08: rw=0, want=1668444976, limit=16208895 Sep 2 20:59:33: dev 08:08 blksize=1024 blocknr=1668444975 sector=-958077346 size=1024 count=1 Sep 2 22:20:42: attempt to access beyond end of device Sep 2 22:20:42: 08:08: rw=0, want=691024436, limit=16208895 Sep 2 22:20:42: dev 08:08 blksize=1024 blocknr=691024435 sector=1382048870 size=1024 count=1 Sep 2 22:20:42: attempt to access beyond end of device Sep 2 22:20:42: 08:08: rw=0, want=691024436, limit=16208895 Sep 2 22:20:42: dev 08:08 blksize=1024 blocknr=691024435 sector=1382048870 size=1024 count=1 Sep 2 22:20:42: attempt to access beyond end of device Sep 2 22:20:42: 08:08: rw=0, want=691024436, limit=16208895 Sep 2 22:20:42: dev 08:08 blksize=1024 blocknr=691024435 sector=1382048870 size=1024 count=1
This is a pain in the b*** since the read() or write() returns EIO (or whatever) and the programs fail strangely.
.config available if needed.
