I started getting hard lockups on my desktop PC with the error "kernel BUG at mm/rmap.c:487" starting with kernel 2.6.13 and continuing through 2.6.14. After switching to 2.6.15 the lockups have continued with the message "kernel BUG at mm/rmap.c:486".

The frequency and circumstance are completely random which originally had me suspecting bad memory but after running Memtest86+ for over 12 hours without error I'm at a loss.

I'm running the binary Nvidia driver so I'll understand if I can't get help here but in searching through the list archives it would seem I'm not alone and I am willing to try any patches that may help diagnose the issue. The crash happens at least daily and I've seen no difference in running kernels with or without PREEMPT enabled.

The machine is a P4 3.00GHz with 2048MB PC3200 Unbuffered RAM on an ASUS motherboard with an ICH5 chipset. XFX GF 6600GT video card, 600W power supply and plenty of cooling.

Below I've included output from ver_linux, syslog and lspci.

Thanks,
Ken
