I am (still) running CVSup'ed to 8/15-04:04:00 on my T22 because I
live my whole life on it. I wanted to wait for the dust to settle
from all the great work Warner Losh et al have been doing to get
everything working.
I'm now considering CVSuping to the latest RELENG_4, and wanted to
know if a couple issues that I'm currently seeing have been seen by
anyone else. I've been following this list from time to time, and
hadn't seen mention of them.
(1) IBSSS + 2 ORINOCO CARDS IN PROMISC MODE = OCCASIONAL CRASH
I have an old PC running 4.3-RELEASE with an ISA PCMCIA adapter
and an Orinoco card set up as my home access point. My laptop
(T22) has the same kind of Orinoco card. Everything works well
normally, but if I do something on both hosts that puts them
into promiscuous mode (like run tcpdump), my laptop will
eventually crash (remember, it's runing -stable as of 8/15 - the
base station is running -RELEASE). Once in a while the
base-station machine crashed as well. No crash dumps either
place. Not sure what's going on, but promiscuous mode seems
to cause problems. I didn't see this listed as a known issue;
is it? Here's a dmesg snippet from my T22:
pcib0: <Intel 82443BX (440 BX) host to PCI bridge> on motherboard
pci0: <PCI bus> on pcib0
pcib1: <Intel 82443BX (440 BX) PCI-PCI (AGP) bridge> at device 1.0 on pci0

pcic0: Polling mode
pccard0: <PC Card bus (classic)> on pcic0
pccard1: <PC Card bus (classic)> on pcic0
...
Example output upon inserting the Orinoco card (I see those
watchdog timeouts and wi_seek messages all the time, btw):
wi0: <WaveLAN/IEEE 802.11> at port 0x240-0x27f irq 5 slot 0 on pccard0
wi0: Ethernet address: aa:bb:cc:dd:ee:ff

wi0: timeout in wi_seek to fc80/0; last status ffff
wi0: timeout in wi_seek to fc80/0; last status ffff
wi0: timeout in wi_seek to fc80/0; last status ffff
Here is dmesg output from the crapoid PC/base-station:
pcib0: <Host to PCI bridge> on motherboard
pci0: <PCI bus> on pcib0
...
pcic2: <Vadem 469> at port 0x3e0-0x3e1 on isa0
pcic2: Polling mode
pccard0: <PC Card bus -- kludge version> on pcic2
pccard1: <PC Card bus -- kludge version> on pcic2
... The card is always in, this is after pccardd gets started
wi0: <WaveLAN/IEEE 802.11> at port 0x240-0x27f irq 3 slot 0 on pccard0
wi0: Ethernet address: 00:02:2d:0a:55:d6
wi0: failed to allocate 1594 bytes on NIC
wi0: tx buffer allocation failed
wi0: failed to allocate 1594 bytes on NIC
wi0: mgmt. buffer allocation failed
I see that lats message fairly frequently. As I said, 4.3-RELEASE
(from CD's just last night, all I did was rebuild the kernel
to get IPFILTER/IPNAT and a couple other things).
On the T22, I can leave the card in promiscuous mode normally
without problems (i.e. on other wireless networks where I'm not
using IBSS mode); it's only at home that I see these crashes.
(2) T22 SOUND STOPS WORKING ACROSS SUSPENDS
Sound on the T22 does not work across suspends; I get the familiar
"dead channel" message. I hadn't seen this listed as something
that had been fixed.
pcm0: <CS461x PCM Audio> on csa0
Other than that, my T22 has been remarkably stable running on the 8/15
source. It stays up for days at a time, many card inserts and
ejections (all on slot#0 (top), though), on battery or plugged in,
across suspends, etc. Great job, guys!
Pax,
