Hi all, since 2.6.24 I find this message on the console. The message is displayed very randomly (or, I cannot find any related event), once or twice a week. irq 71, desc: ffffffff803fccf0, depth: 1, count: 0, unhandled: 0 ->handle_irq(): ffffffff80069510, handle_bad_irq+0x0/0x2c0 ->chip(): ffffffff803f6610, 0xffffffff803f6610 ->action(): 0000000000000000 IRQ_DISABLED set IRQ_NOPROBE set from what I understand, this is an irq related to serial line ttyS1. On this line I have a modem managed by hylafax, but those messages are displayed even when there is no activity on the modem line. Bye, Giuseppe
