I had similar problems with the DS9490 Dallas USB 1-wire adapter. It's a
USB issue of some kind - unplug and replug the DS9490/DS2490 and you can
restart. I could not take the time to find and fix the root cause, I
just replaced it with a USB serial adapter (FTDI) and a DS9097U. No
problems after that. No, it's not as 'clean', but it's not like the
1-wire bus is fast enough to keep up with USB anyway.

i installed *owfs* 2.7p38-1 on my *unslung* nslu2. (unslung 6.8)
i also installed *temploggerd* for monitoring 8 tempsensors.
I did a full upgrade by ipkg update and ipkg upgrade
The 1-wire interface is usb based on ds2490 , all the counters and
ds18s20 are connected directly to this interface (no sub networks)
I tried to read 2 DS2423 counters (so 2 times A and B) with a script on a
5min cronjob.
First I tried owread and then the fusemounted (cat
/tmp/1wire/sensor_name/counters.A) 4 times after each other, with some
mysql
stuff between them.
This both works for some time, but both methods crash te owserver after a
random time. (sometimes 1min, sometimes 5min, or other)
The webpage is still active, but it lost the whole 1-wire bus
The fuses are also empty
when it is crashed i cannot use kill-*owfs* (error: fusermount: failed to
unmount /tmp/1wire: Invalid argument), and lsmod | grep fuse shows fuse
active.
fusermount -u /tmp/1wire does not work either.
after this i can restart the owfs server by run-owfs
I tried downgrading owfs to 2.7p32-2 but it seems to be the same problem
Can anyone help me to get this problem solved?
I can provide more info if u can tell me how
