Hi: So I took a look at the support tickets page and *wow* you guys must be swamped. Is there any way to route tickets to me for i2c-sis645 only (for now)? I have no idea what the backend interface can do. Anyway, here are some comments for tickets that I saw when I searched on "sis645", "bach", and "asb100"... #1293 - I'm sorry to say I don't believe this user's running kernel config matches the one against which sensors were built. The two offending undefined symbols are clearly wrapped with #ifdef CONFIG_HOTPLUG in the code. #1237 - Looks like the same problem to me, at least w.r.t. i2c-sis645. I don't know about the rest though. #1133, #1161 - I was able to confirm with sajmmiller at yahoo.com that his suggested workaround - load i2c-sis645 *before* sis900 - does indeed solve the problem. I suspect that the real solution is to move the magic PCI space bit-frobbing into pci/quirks.c like I did for 2.5; I can't prove it because I don't have the builtin network device and I haven't yet found someone who does who is willing to boot 2.5. #1108, 1124 - The Asus "BACH" chip aka asb100 is I2C bus only. These two users either have a currently unsupported I2C bus or (in the case of the P4PE user) an Intel chipset for which Asus has lovingly hidden the I2C bus PCI device w/ broken BIOS. A fix for this was mentioned here: http://archives.andrew.net.au/lm-sensors/msg02724.html Regards, -- Mark M. Hoffman mhoffman at lightlink.com
