1-systeme hangs when i try ton compile anything
i've compiled the kernel 2.4.4 , once i finish and boot the first time on
2.4.4 everything goses ok ,
only too problemes
1st- klogd takes 100% CPU time
2nd- cat /proc/cpuinf --guives me too CPU'S without putin any info about
the CPU 1
like that approximatively

Old old versions of klogd had bugs where they would do that. If there is
a continuous problem it may also do so - does 'dmesg' show anything ?

Im not sure I follow the description - can you explain more.

I don't think it's limited to "old old" versions. Version 1.3 would hit
100% CPU (DoS-style) when it received NULL bytes IIRC.

Some versions of the 3c59x driver emit a NUL character on bootup which makes
klogd suck CPU. This is fixed in 2.4.5, dunno about 2.4.4.

sysklogd 1.4.1 changelog lists a no busyloop fix.

Check out: http://bugs.debian.org/85478
"When klogd's LogLine() function encounters a null byte in state
PARSING_TEXT, it will loop infinitely. More precisely, copyin()
will treat the null byte as a delimiter - unlike LogLine(), which
will invoke copyin() ever and ever again."
Kinda off-topic, but I just wanted to prove that the bug was in klogd and
not the kernel. :)

The kernel definately shouldn't communicate with the user using NUL chars.
