>Description:
2.2-GAMMA-970205 GENERIC kernel with Adaptec AHA2940 (ahc)
                                                      ^^^  
When I use Tape drive (HP3548A), OS was failing down (and reboot), during
dump to large filesystem (about 1GB).

This probrem have occured using ``dump'' or ``tar''.
This probrem cannot trap with DDB or kgdb. It don't drop into DDB. Just 
fail and reboot.


On 2.2-Beta. 

This probrem may not occur. (I have never seen.)


On 2.2-GAMMA-970205 GENERIC kernel with Adaptec AHA1522A (aic)
                                                          ^^^
This probrem may not occur. 

	

>How-To-Repeat:
Write large data to my tape drive. OS must failure and reboot.

I try 5 times and 5 times failed.
