[ramfs] PANIC: vm_page_fault: unhandled page fault in kernel space

Reported by: bipolar Owned by: nobody

Component: File Systems/RAMFS Version: R1/beta5

Description

While using haikuporter to build the mozc recipe (with OUTPUT_DIRECTORY pointing to a RAMFS mount), on beta5+125, 64 bits, bare-metal, I got the attached KDL (syslog didn't retained the info upon reboot).

The build had almost ended, but haikuporter was unable to unmount the system volume from the chroot, so I did it manually, removed a boot/system dir that remained on the chroot, tried to run hp -F mozc, and that is where I got the KDL.

Looks like a NULL dereference after OOM.

FWIW, I have 8 GB of RAM on that machine, and while building the recipe, RAM usage topped at 3.2 GB. The largest I've seen for that particular work dir during build, was about 1 GB. Even doubling that... should still have a couple of GBs left. But I have no idea how accurate those numbers are (of if there are other "hidden" uses of RAM).
