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:
