Hello,

After fresh installation of FreeBSD 2.1R on 3 boxes with hardware:
   UMC486SX/40, ISA-IDE, [ET Synhronus Interface,] HDD {IDE-WD|SCSI}, 
   Ethernet {SMC|3COM}.
I found that 30 hours (and some minutes) after restart the /etc directory is not
visible on above systems.

Here is example:
 (sesion open before /etc problems)
 rigel# ls /etc
 /etc
 rigel# ls -l /etc
 ls: etc: no such file or directory
 rigel# cd /etc
 (from this moment /etc is visible for some time)

When I replace any UMC486SX/40 with INTEL486DX/50 (running at 40MHz) 
all works excellent.
It has 100% regularity.

Have you got any suggestions?

Thanks in advance,

Piotr Sroczynski
