[glux] What?!

[Maxxer]

Ciao
sul mio pc di casa ho appena installato Debian.
Ho anche utilizzato un Kernel 2.6 ricompilato da me (...).
Sia col 2.6.3 che con il 2.6.7 ho visto strani errori. Oggi ne ho 
"beccato" uno in dmesg:

Assertion failure in journal_next_log_block() at fs/jbd/journal.c:539:

Ho fatto qualche bella opera nella compilazione o c'è davvero qualche 
problema nel kernel?
ciao grazie
