nfs mount stalled, and kernel oops
Posted: Sat Apr 03, 2010 2:51 pm
Hello,
I've 2 issues, but I'm not sure is they are related:
- I'm am able to browse nfs shares, but if I try to open a file, the system stalls. I've made some tests in telnet session: the df commands take several seconds to display the nfs mount points. And a dd if=/some/nfs/file of=/dev/null count=1 doesn't complete.
- taking a look at he demsg output, I noticed a ugly error message, pasted below.

The network works fine, and the nfs server is fully responding when I connect to it through my laptop...
Any hint welcome, can make some more test/report if needed
