About the pentium-bug fix in 2.1.63:
When syslogd/klogd is not running, the bug cannot be reproduced.
When syslogd/klogd is running, running a pentium-bug trigger results in the following situation:
If I'm running X, everything locks up.
If I'm not running X, the system also stops working after displaying the following two lines on the console: <c2800fc8/c2800f8> <handler c01098c0... ...done>
Pressing ctrl-scrollock reveals the following lines (among others): syslogd -11 R current 0 134 1 143 20 klogd 10 R C1E5DF30 0 143 1 164 134 pentiumbug 21 R C008B050 0 520 496
About my system: Intel Pentium 133 (as far as I remember) Redhat 4.9.1 (glibc2) Kernel compiled with egcs-2.90.14p 971023 (I know that I should be using a 'stable' gcc for this to be of general interest, but I still haven't found out how to have both compilers on my system)
By the way: What's the nature of the bug-workaround? Does it bring down performance? (I haven't had time for benchmark tests, and I'm too un-used to my current system configuration to be able to feel a difference.)
