Another thing to think of is that you may have to rebuild the initrd/initramfs after editing /etc/modprobe.d/i2c_i801.conf if i2c-i801 happens to be part of it (and make sure that /etc/modprobe.d/i2c_i801.conf is indeed included in initrd/initramfs then.) > > My system boots legacy grub in text mode (KMS) and seems to keep hanging > > even with that option set. > > Your cold boot hang is in legacy grub itself?

I recall reports about hangs when we first added support for interrupts. I think we addressed all the bugs in this area since then but maybe not. So you may want to try disable_features=0x30 to disable both interrupts and SMBus Host Notify. -- Jean Delvare SUSE L3 Support
