adaptec ANA-6911A/TX: Too much work during an interrupt & Tx-hung

[Leslie Kuczynski]

Hello,

I am using an adaptec ANA-6911A/TX on a 686 running RedHat 6.0 
with th 2.2.11-4 kernel.  The Ethernet card is sharing interrupt
9 with channel A of a dual port scsi card (adaptec AHA-3944AUWD).
Channel B reports using interrupt 15.  The box also contains 
2 3Com Ethernet ISA cards (interrupts 10 and 11) running as 
eth0 and eth1 respectively.  The adaptec ANA is running as eth2
with the tulip.c:v0.91g driver.

After a period of time (hours to a few days) the adaptec Ethernet
card hangs reporting "Too much work during an interrupt" and 
"Tx hung". 

I have provided some information below from the system log and 
from tulip-diag.  If more info is needed please let me know.

Any help in this matter is appreciated.

Best regards,
Leslie Kuczynski
