Solved! It turned out the problem was in the external PCI adaptor I'm using to increase the (rather limited) number of legacy 32-bit PCI slots in my server system through a PCI-Express slot (http://www.virtuavia.eu/shop/pci-express-to-pci-expansion-box-p29809.html) Although the card did get properly detected, it was very unstable, constantly crashing the kernel. I've removed the external PCI expansion box, plugged the card directly in the only on-board PCI slot and now it works perfectly stable. Lessons learned: don't buy these external PCI expansion boxes.
