kernel 2.6.19 and RealTek RTL8139 interrupt

[Oleg Mikheev]

Hi guys,

I'm using FC5 with vanilla kernels.
Everything worked great until 2.6.19 was released.
Not each time I'm trying to up my eth0 kernel produces this:


eth0: link up, 100Mbps, full-duplex, lpa 0x45E1
irq 18: nobody cared (try booting with the "irqpoll" option)
 [<c01391aa>] __report_bad_irq+0x36/0x7d
 [<c0139379>] note_interrupt+0x188/0x1c3
 [<c0138a19>] handle_IRQ_event+0x1a/0x3f
 [<c01396ca>] handle_fasteoi_irq+0x61/0x73
 [<c0104e34>] do_IRQ+0x6b/0x83
 [<c0120c76>] sys_rt_sigprocmask+0x80/0x93
 [<c01034a2>] common_interrupt+0x1a/0x20
 =======================
handlers:
[<c0257416>] (rtl8139_interrupt+0x0/0x3aa)
Disabling IRQ #18


I'm posting it here b/c I don't think it's a normal behavior.
Here is the diff of dmesg output between 2.6.18.3 and 2.6.19:
