nel passaggio di versione alla 10.04 ho riscontrato un fastidiosissimo problema (forse bug) su acpi/kernel.
Dopo qualche decina di minuti di utilizzo della mio so preferito acpi si blocca (non riconosce più i cambi di alimentazione, non si regola più la luminosità dello schermo, etc etc) e parte un flood sul dmesg, di questo tipo:
Codice: Seleziona tutto
[ 767.208058] ACPI: EC: input buffer is not empty, aborting transaction
[ 767.208072] ACPI Exception: AE_TIME, Returned by Handler for [EmbeddedControl] (20090903/evregion-424)
[ 767.208106] ACPI Error (psparse-0537): Method parse/execution failed [\_SB_.PCI0.LPCB.EC0_.GBST] (Node f7017030), AE_TIME
[ 767.208197] ACPI Error (psparse-0537): Method parse/execution failed [\_SB_.PCI0.LPCB.EC0_.BAT0._BST] (Node f7017120), AE_TIME
[ 767.208277] ACPI Exception: AE_TIME, Evaluating _BST (20090903/battery-393)
Cercando di riavviare (o di spegnere e poi riaccedere il pc), succede che non si accende nemmeno la macchina, unica soluzione: togliere la batteria!
Qualcuno ha qualche idea sulla soluzione?Io avevo pensato a un downgrade di kernel.
PS: Allego un pò di materiale
PC: notebook aspire 5930G
