Hi I've also saw the same issue with my shared IRQs (and also IRQ was shared with nvidia graphics card). If you look in your dmesg, it suggests you to boot with "irqpoll" option. As for me - this didn't help until I added also "noirqdebug". After that I'm running already 6 days without problems and required reboots (before that I had to reboot every day). If this doesn't help, I also saw suggestions to boot with "noapic" option (as non-preferred).
Important : apic is essential http://wiki.osdev.org/APIC"APIC ("Advanced Programmable Interrupt Controller") is the updated Intel standard for the older PIC. It is used in multiprocessor systems and is an integral part of all recent Intel (and compatible) processors. The APIC is used for sophisticated interrupt redirection, and for sending interrupts between processors. These things weren't possible using the older PIC specification. "
