Your current kernel will also have new unknown troubles, plus quite some known troubles. Not upgrading doesn't mean you have no unknown troubles, only different unknown troubles. > Before I'll upgrade to new version I'd > like to try finding the reason of this behavior. Tracing already fixed bugs is a waste of time. The best way to avoid that waste is to upgrade your kernel and see if that fixes the problem. > Moreover the upgrading to > new kernel couldn't solve the issue.

When the kernel hangs, try to figure out what's going on with one of the magic sysrq commands. BTW, "2.6.21-7" suggests you're using a distro kernel. Check if your distributions offers a kernel upgrade. Erik -- They're all fools. Don't worry. Darwin may be slow, but he'll eventually get them. -- Matthew Lammers in alt.sysadmin.recovery
