Description Emilio Granados 2007-09-14 13:30:01 UTC

Cuando se realizan muchas escrituras o alguna grande a una partición ext2fs ( ext3 ) en amd64 con FreeBSD el kernel se congela. La partición de FreeBSD está en un disco IDE primario como master: /dev/ad0s2a.
La partición de ext2fs está en un disco SATA-1 en una partición extendida: /dev/ad8s6.
Salida de mount:

/dev/ad0s2a on / (ufs, local)
/dev/ad8s6 on /media/datos (ext2fs, local)

Si se realizan las escrituras desde un terminal de texto, al congelarse el kernel aparecen en la pantalla caracteres sin sentido que la llenan al completo.

Salida de df -h :
/dev/ad0s2a     13G    4.3G    7.3G    37%    /
/dev/ad8s6     188G    116G     62G    65%    /media/datos

Desconozco si el problema está en que es una partición ext3, si es por que está en un disco SATA o si es porque es una partición extendida.

How-To-Repeat: Simplemente realizar muchas o alguna escritura grande en una partición ext2fs.

If my Spanish isn't broken, the OP meant:

The kernel freezes when several writes or some big ones are made in
a ext2fs (ext3), in a FreeBSD amd64.  FreeBSD's partition is in a
primary-master IDE disk (/dev/ad0s2a).  The ext2 partition is in a
SATA-1 disk as an extended partition (/dev/ad8s6).

mount output:

/dev/ad0s2a on / (ufs, local)
/dev/ad8s6 on /media/datos (ext2fs, local)

If the writes are made from a text terminal, a lot of meaningless
characters fill up the screen when the kernel freezes.

'df -h' output:

/dev/ad0s2a     13G    4.3G    7.3G    37%    /
/dev/ad8s6     188G    116G     62G    65%    /media/datos

I'm not sure if the problem is due to an ext3 partition, or because it
is in a SATA disk, or because it is an extended partition.

Simply make lots of writes or some big ones in an ext2fs partition.
