Sorry for the bogus message last time. Fellow FreeBSDers, I'm experiencing a pretty nasty panic on FreeBSD 2.1-stable, and I wanted to see if anybody else out there is having a similar problem. I have several times now had the kernel panic and report kernel: panic: vinvalbuf: flush failed. This immediately follows a message that reads: kernel: biodone: buffer already done. The sequence that leads up to this situation is always the same: a person will be using mail(1) the manipulate his mailfile. The kernel will issue the biodone message. Then any subsequent action by the user will put his process into an infinite wait, with the wchan set to "vmopar". The process could wait there indefinitely. However, when anyone tries to read that mail file, either with /usr/bin/mail or elm (or, presumably, whatever), the kernel panics. We're running 2.1-stable taken from the tree on Dec 6, 1995. Since there had been some improvements to the Adaptec driver and some work on the VM locking mechanism, we've built a kernel using sources sup'ped on Feb 13. If anyone is experiencing similar problems, (even just the biodone messages), please contact me at ejon@zipnet.net, and please cc the message to both wink@tiac.net and ejon@tiac.net. We're building a pretty big ISP and want to run it on FBSD, but stability is paramount to our success. Eric Jones
