Hi, When my machine boots after a panic (which happens to frequently lately) it failes to save the kernel core file. This makes it very hard to debug the problem. The machine has 512MB of RAM as you can see. The console output is: .... Checking for core dump: dumplo = 537526272 (1049856 * 512) savecore: reboot after panic: page fault Jan 21 12:30:06 localhost savecore: reboot after panic: page fault savecore: system went down at Wed Jan 21 12:23:45 2004 savecore: writing compressed core to /usr/crash/vmcore.16.gz savecore: /usr/crash/vmcore.16.gz: Illegal seek Jan 21 12:30:06 localhost savecore: /usr/crash/vmcore.16.gz: Illegal seek savecore: WARNING: vmcore may be incomplete ....

Any obvious misstake I'm doing? /jonas
