Hi, I have motherboard with SIS 756 + SIS 964L chipset (Asus A6Km-Q010 laptop). If any USB device is pluged in, system get stuck while booting up, see dmesg. Same problem has Gentoo 2005.1 and 2006.0 instalation CD for AMD64. Other observed problems with USB: 1) USB support has to be compiled as a module and modprobed later on. If it is build into kernel, booting get stuck even without plugged USB devices (I think here, the problem is with ehci-hcd driver). 2) Gentoo 2006.0 installation CD has to be run with "nousb" option, otherwise only blank screen appears after bzImage load and system get stuck. USB drivers are modprobed automaticaly later on anyway.

Hmm, I found that it might be a BIOS problem. See https://launchpad.net/products/linux/+bug/36583 http://bugzilla.kernel.org/show_bug.cgi?id=6208
Are there any bios updates available?
As far as I found, there are bugs in DSDT even in newes BIOS updates. It seem fixing DSDT helps to solve this problem.
Is that a "no, there are no BIOS updates available"?
There are new BIOS updates available for this laptop. Unfortunately,they still contain bugs in DSDT, particularly in USB part, and linux cannot handle it. I found that several other people experienced the same problem with this laptop with various linux distibutions. I think I'll mark this bug as fixed because it's not a problem of linux but Asus developers. USB problems can be solved by repairing DSDT and compliling it into kernel or by initrd DSDT overide. There is how to on http://gentoo-wiki.com/HOWTO_Fix_Common_ACPI_Problems Regards Pavel
