On my (single processor, non-acpi) system the kernel now completes
booting, but savecore receives a signal 11 after having saved about
235 MB, and all(?) processes after that get a signal 11 or 10 until
finally there's a "panic: bad peter". This is absolutely reproducible.
Is there any additional information I should provide?
Bye, Philipp
