Hi,
I've been having some problems with my an0 device and 5.2-RC1,BETA. 5.1-RELEASE
worked great.
I am able to get an IP from my AP's dhcp server, and sometimes I can transfer
some data. However it seems that at random my system freezes up partially.
I get:
an0: failed to allocate TX descriptor
BUSY
an0: failed to read RID ff50 0 0 0 0, 3
BUSY
...repeated very slowly.
For all I know it could just be my keyboard that's being frozen. I had my lid
light on, and I wasn't even able to turn it off.
My guess is I have some interrupt related problems, as I've had them in the past
with my fxp0 device, but I haven't been able to figure out how to logically
solve the problems. I thought I'd better post just incase... I'd also like 5.2
to be a great release!
Here's some information:
vmstat output:
%vmstat -i
interrupt total rate
irq0: clk 171531 99
irq1: atkbd0 3955 2
irq8: rtc 219564 127
irq9: acpi0 93 0
irq11: cbb0 an0+++* 150927 87
irq12: psm0 42 0
irq13: npx0 1 0
irq14: ata0 127217 74
irq15: ata1 31 0
Total 673361 392
I'd like to know how to read this, but the manpage didn't seem to help me much.
