[hylafax-users] IRQ Overload

["Shane Eckert" <shane.eckert@xxxxxxxxxx>]

Hi,

 

We are using Hylafax on two servers with 8 port PCI modems. (single card IQ Express 8 port)

 

Things were going just fine until both servers were unable to initialize the modems. After awhile dmesg was flooded with the following messages.

 

Jun 23 17:41:42 s_sys@util10 FaxGetty[27504]: LOCKWAIT

Jun 23 17:41:42 s_sys@util10 kernel: serial8250: too much work for irq201

Jun 23 17:41:42 s_sys@util10 kernel: serial8250: too much work for irq201

Jun 23 17:41:42 s_sys@util10 kernel: serial8250: too much work for irq201

 

And so on for several hundred lines.

 

Shutting down the server and reseating the PCI cards fixed the issue. Nothing else would do so.

 

I fear this is a temporary fix since the IRQ’s were overloaded.

 

Any ideas?
