Partizioni Reiserfs e buffer layer error kernel 2.6.0-test9
Hi all,
trastullandomi con il portatile (HP VT6200 con disco HITACHI_DK23DA-40) su
debian unstable e immagine kernel 2.6.0-test9 ho notato grossi problemi nel
trasferimento da partizione a partizione di file di media/grossa dimensione
(50 up to 700 MB), ovvero rallentamenti mostruosi e carico della macchina che
raggiunge valori tra il 3 ed il 5.
Improvvisamente mi sono ricordato di una serie di errori con relativa Call
Trace, che vedevo all'avvio della macchina.
Vi riporto il contenuto di kern.log relativo all'ultimo boot:
Nov 16 09:29:39 magoo kernel: buffer layer error at fs/buffer.c:431
e poi segue il Call Trace (che mi fa supporre che ReiserFS sia in qualche modo
coinvolto)

Avete qualche indicazione in merito?
