2Don, I think the priority of interrupt handling is not the problem, the race conditions are. I've never had this problem on single-core CPU. Unloading most of ACPI stuff will solve the problem, however this is a nasty solution (I've laptop and use events of ac/battery for energy profile changes).
It might be also the problem of keyboard itself, the firmware that acts odd... In windows I get shift/ctrl/alt stuck every 2-3 hour, especially if Firefox + Zend studio are loaded. Wit the latest patches (auto-install 2-3 weeks ago) the problem is now appearing even more frequent. Anyway this proves that keyboard is handled differently in Windows and Linux, I've never seen repeating keys (missing ordinary key release) in Windows and stuck control keys (missing shift/ctrl/alt key release) in Linux.
I will try to compile non-preemptive kernel and report results later.''
2David Oftedal no, I dont' see these messages in dmesg.
