I updated my recently acquired core-2 duo laptop to 7-stable amd64 (I had been running 7-stable i386 with few problems) and have acquired an apparent irq problem. Fortunately in debugging a linux shared-interrupt problem about a month ago I learned that the X server will happily accept mouse motion as if it was a display interrupt, so at least with some inconvenience I can read the screen... (the keyboard isn't so obliging) Ours does this too... /usr/src was picked up via svn on last Saturday morning EDT, ports via csup about the same time. I have no idea if this bug is in the intel driver, drm, or the core msi code... There are 2 peripherals that dmesg says uses msi - re0 (which doesn't get a kernel thread indicated in ps for either the stated irq (257) or re0) and drm0/vgapci0 (which indicates irq256 in systat and ps). As I said, this worked properly with earlier source (about a week) in i386 mode. I've used both G45 and re controllers in (f10) linux msi mode with no problems in both 32 and 64-bit. Fortunately this laptop now has enough disk to triple-boot so at least something works... I am using svn instead of csup because I am trying (haven't gotten time yet either :-) to port Sam's ath 92xx code to -stable and handling code porting is much easier that way. -- Pete
