Hi,
While I tried to generate a segfault it crashed GNUMach (1.x, I have
tested both CVS and 1.2) with this error:
panic: zalloc: zone kalloc.8192 exhausted
(There is a small pause here and a bit of disk activity/ flashing IDE LEDs)
hd1: irq timeout: status=0x58 { DriveReady SeekComplete DataRequest }
hd0: disabled DMA
hd1: disabled DMA
ide0: reset: success
(And here my box reboots after some seconds)
Here is how I produced this result (and I can generate this problem
anytime, so it is possible to debug this). The weird thing about this
problem is that it only happens when I run the test program from my
/home partition (which lives on hd0s1).
Here is what I did before GNUMach crashed:
[EMAIL PROTECTED]:~$ cd src/tests
[EMAIL PROTECTED]:~/src/tests$ cat crash.c
int
main (int argc, char *argv[])
{
int *p = 0;
*p = 213;
return 0;
}
[EMAIL PROTECTED]:~/src/tests$ gcc crash.c -o crash
[EMAIL PROTECTED]:~/src/tests$ ./crash
Segmentation fault
[EMAIL PROTECTED]:~/src/tests$ ./crash
Does someone have any idea what the problem might be and how I can
debug this? I am willing to do so but I am afraid that it can be
quite hard (and that I do not have the experience and perhaps not
enough knowledge) so I would appreciate some help (a pointer in the
right direction).
Are other people able to reproduce the same? Please notice that you
will need to test this using a second partition.
Thanks,
Marco
