Re: Bad vnode causing crash in 4.x

2002-07-12 Thread Michael Adler
I meant to ask whether we simply need to add a check for (!dev) before the for loop in vop_revoke() in sys/kern/vfs_subr.c. That would clearly prevent the crash here. What I don't know is whether there is some larger bug. -Michael To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubs

Bad vnode causing crash in 4.x

2002-07-11 Thread Michael Adler
I've been suffering infrequent system crashes when running ange-ftp under emacs for some time and finally have a crash dump from a kernel with symbols. This crash dump was on 4.6-stable, though I've seen the bug off and on for at least a year. All the crashes have the following characteristic

bin/37665: restore does not recover uid, gid, etc. of symbolic link

2002-05-02 Thread Michael Adler
/sbin/restore currently does not set the uid, gid, mode or times of symbolic links. In particular, the owner of the link is left as the owner of the restore process. Would someone consider checking in the patch I supplied in: http://www.freebsd.org/cgi/query-pr.cgi?pr=bin/37665 The patch is

Thank you for the tuning page! I and, I fear, others made the mistake of assuming that because SOFTUPDATES is in the kernel that it is automatically enabled for the disks. Nothing printed during boot leads me to believe otherwise and no mention was made of checking the flag using tunefs in /

Re: The future of multiprocessors (was: SMP in 2.4 (fwd))

2001-04-19 Thread Michael Adler
A number of our larger customers care about computation/cubic foot. The density of processors is important to them. SMP machines work well here. A future Alpha processor will be an SMT (symmetric multi threaded) machine. Above the lowest levels, it will look like a multi-CPU machine. The m
