Ok. For a temporary fix, there ya go. But removing pci_enable_device is incorrect; it merely avoids what appears to be a bug with your Via irq routing. Would it be possible for you to edit linux/arch/i386/kernel/pci-i386.h, and change the line near the top from #undef DEBUG to #define DEBUG 1 and then send the output of 'dmesg -s 16384' to linux-kernel (and CC me)? That will dump your PCI IRQ routing information, among other details. Step two, "modprobe es1371" with pci_enable_device -in- the code, and with debugging enabled as described above. IIRC it should print out a few more lines of debugging information that will be helpful. Since we are dealing with a hard lock, these last few lines of debugging info might have to be copied via a serial console, or by hand. One last question... is this an SMP machine? If so, let me know if booting with "noapic" option on the command line fixes things.
