I am using 5.0-Current (actually intended to get 4.2-Stable, but anyways)... It appears there is a problem with the way the system is dealing with the mouse, keyboard, and sound devices. My source tree was updated via CVSup just a day or so ago, and compiled on that day, with no errors. Kernel has since been re-compiled for my usual settings (changes in the way sound devices are handled was noted and adapted), and of course to trim out some unneeded stuff (SCSI and RAID drivers, etc) Consider this line from the obvious Beach Boys hit (an mp3 playing under mpg123 0.59r): "I wish they all could be california... girls..." At one point, the sound, mouse, and keyboard all stalled in the middle of the word "be". It sounded like: "I wish they all could brbrbrbrbrbrbrbrbebebe california... girls..." At that moment, the mouse stops moving, for as long as the sound stalls, and the keyboard will insert a garbage character to whatever application I am focused on, if I happen to be pressing a key at that moment. This happens frequently when I move the mouse around, and moreso if something else occurs along with that movement, such as a focus change from one window to another. Occasionally, typing on the keyboard also induces a stall in the sound and mouse drivers. Machine: Compaq Presario 4764. P166 MMX, 24 Megs RAM. Sound: ESS Audiodrive 18xx series on the motherboard, non PnP. Mouse: A typical IBM three-button wheel mouse. Environment: X Free86 3.3.6, Gnome/Sawmill. (Problem is not limited to X, it also happens at the consolem, before X is even started). To me this looks like an IRQ handling problem, but I am not certain. On my hobby platform, IRQ software malfunctions would be the first thing to look for if such a problem were to occur. My applications (mostly ports and packages) from 4.1 have not yet been updated. This same problem also exists in 4.2-Release as obtained via kern.flp and mfsroot.flp images for 4.2-Release, FTP Install. There have been no hardware changes made in several months. In 4.1-Release (also obtained via FTP Install), this problem does NOT exist. I also verified that the problem goes away when 4.1 is present by "downgrading" back to 4.1-Release from 4.2-Release (using a rather brute-force method to insure a clean install). In all cases I have of course obtained kernel source during the install, and always compile it using the same settings (or equivalent, as with sound parameters in 5.0-C compared to 4.1-R). After mentioning my guess about possible IRQ problems in #freebsdhelp on IRC/EFnet, someone suggested I take a look at the output of vmstat -i and dmesg. Here are those outputs: Output from vmstat: interrupt total rate stray irq0 1 0 stray irq6 1 0 stray irq7 1 0 stray irq15 1 0 ata0 irq14 109593 1 ata1 irq15 10 0 fdc0 irq6 1 0 atkbd0 irq1 144561 1 psm0 irq12 107832 1 sio0 irq4 1 0 sbc0 irq5 1051032 12 ep0 irq3 40721 0 clk irq0 8750437 99 rtc irq8 11197886 127 lpt0 irq7 245507 2 Total 21647585 247 Output from dmesg: Copyright (c) 1992-2001 The FreeBSD Project.
