Hi

Just some info in case it helps. Not detailed, but I'm a busy guy... just in
case this helps.

This is with 2.4.18-3

I ran the Oracle installer and it failed for some reason. Nevermind - some
compat libs missing. It happened twice, that's mine to fix. When I exit it
it gives me the
        Jun  5 09:05:55 rlpc kernel: Trying to vfree() nonexistent vm area
(c38a5000)
and a while later the rest. top doesn't work anymore after that and I
rebooted. The whole thing happened again.

I upgraded to

and then the only the

happened.

1. trying to vfree() nonexistent vm area

Hi

I just compiled kernel 2.2.20 with the openwall security patch
on an Compaq DL360 (PIII, 512MB, 800MHZ, Smart Array Controller)
with the following flags:

CFLAGS = -Wall -Wstrict-prototypes -O9 -funroll-loops -ffast-math \
         -malign-double -mcpu=pentiumpro -march=pentiumpro \
         -fomit-frame-pointer -fno-exceptions

When i reboot the box with this kernel i got this error:

checking partitions
dev/ida/ . . . . . . . . .
trying to vfree() nonexistent vm area

after that the machine freezes :-((

Any hints ?

Thanks in advance

Regards
Widmann Thomas
