OK, I have tried again, and it is 100% reproducible at work as well.
At the time it dies, the kernel loops in the procedure : truncate_inode_pages.
It still responds to ping, but does not more.
Here, at work, it happens when I log as danis, issue then a 'su' to get root access, and type 'exit'. Nothing more. Boom.
My home is NFS mounted from a Solaris 2.5.1 box. At home, it happens against a 2.0.36 UNFSD server. I think it did happen as well with 2.2.7-ac4 (I have done a report on it too few days ago).
One more thing : as I typed repetitive ALT-SCROLL to check the registers, I got a bunch of addresses printed on the screens and a : Code: c7 05 00 00 00 00 00 00 00 00 83 c4 08 5b 5e 5f 5d 83 c4 08 Aiee, killing interrupt handler Unable to handle kernel NULL pointer derefere,ce at virtual address 00000001
I think it is due to my repetitive ALT-SCROLL, and I would not bother that much (bad people would simply hit the reset button however).
