Help! I'm going nuts! We have a VAX-11/750 running 4.2bsd and we recently got a DR11W card as an interface to a small machine with a DR11W emulator (looks like a DR11W to another DR11W). I cheerfully started in on the driver for it (has to be a custom driver because some ad hoc protocol has to be done at the driver level to get speed). Trouble showed up shortly after I got it appearing to work. After about 30 seconds of exerciser transfers, someone (presumably the driver) corrupts something and we get messages like (usually inode 2): bad dir entry ino 2 offset 0: mangled entry bad dir entry ino 2 offset 512: mangled entry bad dir entry ino 2 offset 1024: mangled entry bad dir entry ino 2 offset 1536: mangled entry bad dir entry ino 2 offset 2048: mangled entry Shortly thereafter, the system panics (not consistently the same panic) and we crash. Once it managed to write the damaged directory back to disk first and we had to pull the partition off backups. Is there a working DR11W driver out there I could look at for ideas? Or does anyone have any other suggestions? Pretty please?? -- der Mouse System hacker and general troublemaker CVaRL, McGill University Hacker: One responsible for destroying / Wizard: One responsible for recovering it afterward
