gestione IRQ

[Caleb]

ho un problema con la condivisione degli irq... senza preavviso e senza motivo apparente ogni tanto mi si disabilita l'irq 11 assegnato alla scheda di rete e condiviso con l'usb, col risultato che non posso piu' accedere alla rete... a nulla vale tirare su e giu' interfacce e moduli vari, ogni volta devo riavviare; questo uno stralcio di sys.log:

Nov  1 21:53:24 P4 kernel: Disabling IRQ #11

googlando un po' ho visto che il problema e' aggirabile passando noirqdebug al kernel, ma come si fa tramite grub? io ho provato cosi':

title		LFS 2.6.8.1_light
root		(hd1,2)
kernel		/boot/lfskernel-2.6.8.1_light ro vga=ask
noirqdebug
savedefault
boot

ma non sembra avere alcun effetto...

C'eri vicino, te hai usato un'idioma simil-lilo

title		LFS 2.6.8.1_light
root		(hd1,2)
kernel		/boot/lfskernel-2.6.8.1_light ro vga=ask noirqdebug
savedefault
boot

Tutte le opzioni del kernel vanno, separate da spazi, dietro l'argomento di 'kernel'

'azz... mi sono guardato tutto l'info di grub e non ho trovato niente, idem in rete... ora provo, grazie

[Caleb]

dmesg | grep command
Kernel command line: ro vga=ask noirqdebug

sembra che abbia gradito... spero anche sortisca l'effetto desiderato perche' sta cosa mi sta facendo esasperare

Scusate se uso questo 3d per riproporre un mio problema di irq.
Distro: mandrake 10.1
irq: 9
Problema: acpi non riesce a condividere questo irq con usb e altro nè a "prendersi" un diverso irq.
Naturalmente è tutto ok con acpi=off in lilo, ma siccome è un portatile, ci terrei molto ad avere un acpi funzionante.

Dite che posso senza rischi provare a mettere anche io noirqdebug in lilo??

Ciao!!!

[Caleb]

no... stavo giusto per riportare su il thread

con noirqdebug (che ho tolto) non ci sono problemi di perdita di indirizzi assegnati, in compenso non appena collego qualcosa alla usb il pc si inchioda

non ne vengo a capo

[altor]

Stasera provo e faccio sapere se l'effetto è lo stesso anche nel mio caso...

Ciao!
