Recently, I had two different problems: a. For a problem that started since somewher after 2.6.24-rc9 till now, even with the sched-devel git version, the keyboard on entry on my laptop will jump/skip some characters. Sometimes even repeating many times SUDDENLY when I just entered once. That is for Dell Inspiron 9300 (Intel ICH6 chipset, ie, already > 3 years old, with FC7 as the OS). But no such problem for desktop (Intel/AMD alike). But I don't know what to capture in the kernel when such thing happened. b. For my Intel desktop (FC7, 2.6.25 as the kernel), few days ago it just go into an extreme sluggish response mode....both mouse/keyboard input will take a long time to response. I really don't know how to capture a snapshot of the kernel at that point. It only happened after running some heavy stuff like database server + firefox downloading etc. c. Occasionally, my swap device will get disconnected, or corrupted, and then the system (after some use) go into an extreme sluggish response mode as well. What happened? Key question: How to debug such problem? How to capture kernel's state when everything hanged? How to capture the bootup message when it crashed upon bootup?
