Subjectserious filesystem corruption (2.4.16/MediaGX/ext2/CF card)
Date
From
Greetings all,

I have an embedded box which is having an absolute fit at the moment. I have
a 48 MB Sandisk Compact Flash card with a single ext2 partition, running on
a Lippert Cyrix MediaGX-based PC-104 board. Certain activities cause it to
explode, for example find / will do it nicely - the following is a condensed
dmesg output (full thing on http://ieee.uow.edu.au/~daniel/explosion.log)

VFS: Disk change detected on device 16:00
/dev/ide/host0/bus1/target0/lun0: p1
VFS: Disk change detected on device 16:01
VFS: busy inodes on changed media..
/dev/ide/host0/bus1/target0/lun0: p1
VFS: Disk change detected on device 16:00
invalidate: busy buffer

[repeated many times]

/dev/ide/host0/bus1/target0/lun0:hdc1: bad access: block=12222, count=2
end_request: I/O error, dev 16:01 (hdc), sector 12222
hdc1: bad access: block=32840, count=2
end_request: I/O error, dev 16:01 (hdc), sector 32840

end_request: I/O error, dev 16:01 (hdc), sector 12222
hdc1: bad access: block=12236, count=2
end_request: I/O error, dev 16:01 (hdc), sector 12236
hdc1: bad access: block=32838, count=2
end_request: I/O error, dev 16:01 (hdc), sector 32838
EXT2-fs error (device ide1(22,1)): ext2_write_inode: unable to read inode block
Remounting filesystem read-only

The disk-change thing doesn't sound real healthy.

kernel is 2.4.16 (compiled with MediaGX optimisations - .config is on
http://ieee.uow.edu.au/~daniel/kernel.config)

gcc is 2.95.4

binutils is 2.11.90.0.24

Please CC me as I'm not currently on LKML.

Thanks,

- Daniel
