:/usr/obj isn't mounted, i'm just compiling a kernel.
:
:no i have no msdos mounted filesystems, i do however have an
:unmounted win98 partition and a cdrom with joliet extentions mounted
:however the cdrom only contains mp3s.
:
:After doing more data manipulation (copying files around to flush
:the NFS cache) it seems to reload the data then it finds them ok
:and tries to link, during the link i get missing references to
:several symbols, symbol sizes changed etc etc...
:
:Just seems like bad data.
:
:Now if i just go into the dir on the server and link the kernel
:it's fine, no problems whatsoever. (compile on local disk)

:NFS perfomance and stability in 3.1-stable and 4.0 have been surperb lately.
:one reboot when i was killing a low ram NFS server a few weeks ago and just
:this today (which could be the NIC) otherwise very impressive.
Ok. This is something to watch, then. The corruption is worrysome. It
is odd to get this sort of corruption in a client's buffer cache when
all the file I/O is running over NFS. The real question is : where did
the corruption come from? The client's IDE drive or something originally
on the server?
Are there any dos partitions on the server at all? If not, then the
corruption is occuring on the client. But if the make procedure is not
accessing (much of) the client's hard drive, where on the client could
the corruption be coming from?
