HI, 

I just installed redhat 5.1 running the 2.035 kernel with a token ring 16/4
isa adapter. 
I was running slackware with tr kernel support working just fine. My
problem with redhat is the following:

tr0: ISA adapter found using irq 3, PIOaddr a20, 16k shared RAM.
tr0: Hardware address : 08:00:5a:88:60:4d
tr0: initial interrupt : shared RAM located at 000D80E2.
tr0: Unknown command 88 encountered
tr0: Unknown command 01 in arb (repeating....)

Thanks in advance.
