I got the following with kernel 2.2.2 (on an upgraded Red Hat 5.2
system). The hardware is AMD K6-2/333, 64MB PC100 SDRAM, Adaptec 2940,
3c900, and ATI Mach64 GT video. I wasn't doing anything special, I just
had X running with a couple of xterms and netscape (communicator 4.5).
I wasn't doing anything in netscape, I was typing in an xterm that was
rlogined to another system.

I don't speak for anybody but myself - that's enough trouble.
