ho un pavillion dv6159eu con kernel 2.6.27-11 (Intrepid). Passando ad intrepid ho avuto un po di problemi con le usb che ho (spero) risolto levando l'opzione "noapic" di avvio al kernel. Per avere + dettagli vi rimando al mio precedente post http://forum.ubuntu-it.org/viewtopic.php?t=259965
1)La wifi in modo (sembra) random non viene rilevata in avvio neanche caricando manualmente il modulo b43 e devo riavviare
per tentare di sistemare ho messo "b43" in /etc/modules ma il problema persiste (random)
2) inoltre sembra che la mia wireless non funzioni qnd collego/scollego il cavo di alimentazione e lavoro con la batteria. Non sono sicuro che questo avvenga di preciso in questi istanti. Cmq, ho aggiornato il firmware della mia broadcom(4311) basandomi sulla guida su linuxwireless http://linuxwireless.org/en/users/Drivers/b43 .
All'avvio ricevo errori tipo "eth1 error fetching device interface device not found" e questo è il mio dmesg in corrispondenza degli istanti in cui la mia scheda scompare nel nulla :
