Subject: page reserved twice

Message-ID: <3B42610F.29D004FF@idcomm.com> (raw)
I'm curious if there is any significance to this, which occurs at each
reboot on an SMP system running noapic (sometimes Netscape manages to
produce a hard lockup on the system, sometimes a core dump indicates NS
had signal 7, bus error, in cases where it doesn't lock the system),
2.4.6-pre1 with XFS patches:

Very similar messages seem to occur on a different machine with RH's
2.4.2 kernel, BX chipset, and IO-APIC enabled. The machine this is from
has had this message on earlier kernels as well, none of which had XFS
patches. What is the significance (or consequence) of pages reserved
twice?
