The commands _work_ with a coldstarted Linux and i2c-piix not loaded, so the only thing I can do is blacklisting it and renounce sensors support, having a good a argument for a new hardware aquisition. :) For completness the message with the SMBus revision, which is not the pci-revision, is: SMBus Host Controller at 0x1040, revision 0 The "?" at the interrupt line of lspci is a little strange: >> Interrupt: pin ? routed to IRQ 9 looking at lspci -x -s 7.3 I can see that PCI_INTERRUPT_PIN == 0 I cant see that i2p-piix does any interrupts, refering /proc/irq/9/spurious The driver says: Using Interrupt SMI# for SMBus I'm not sure, but my box @home has the same lspci output with the "?". So long, thanks for help.
