I don't normally have any Freebsd binaries on my Linux partitions. But as a test, I copied a few and ran them. It wasn't a real stress test, but ls, emacs, xv and xsnow all seemed to run ok on ext2fs. So, I guess that's not the problem. It seems to require the combination of a Linux binary and ext2fs. And it's not a complicated Linux binary. I can produce the panic with Linux's ls. On the other hand, I have successfully run the Linux versions of emacs and netscape, as long as all the files are on ufs. I know this works for other people, and that's what's so baffling. The symptoms point to me misconfiguring something. But I install linux_base-6.1 and load the module (with the linux script), and it's ready to go. There aren't any rc or sysctl variables for me to screw up. Are there any configuration options for the Linuxulator that I might have set wrong? I blew away /compat/linux and reinstalled linux_base, just to make sure it wasn't any additional libs that were the problem. Is Linux emulation or ext2fs sensitive to any kernel options (other than EXT2FS)? I'm not using soft updates, if that matters. And to make sure it wasn't bad sectors on the disk, I tried the ext2fs slice on two disks. And it panics on both. --Mark To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-fs" in the body of the message
