Since this I my first post here, I will first take the opportunity to
thank the free software developers who read this. I have used Linux
almost every day for more than two years. My new computer, a PPro,
uses Linux as it's only OS. I have tried a 2.1.48 kernel for a few
hours, it works much better than the last 2.1.xx kernel I tried, but:
First a minor problem: When running large jobs in the background, the
machine suddenly freezes up for a few seconds while swapping, making
even typing text impossible. The 2.0 kernels does not behave like that.
Secondly (this may be a more serious problem),
something odd happened to one of my data files:

What is the "^@^@^@^@" doing in there? It was not there 2 minutes ago
when I used it as input file to a CFD post processor. No one has
edited the file (confirmed by the time stamp). The file was on a 2MB
e2fs partition on a Quantum Fireball.
And finally: Several problems with NFS
(mounted partitions from a HP file server):
NFS seems slow and complains a lot about:
Aug 8 13:29:08 immpc17 kernel: NFS: short packet in readdir reply!
And sometimes:
Aug 8 08:56:13 immpc17 kernel: NFS: giant filename in readdir (len 40e5ddc1)!
Aug 8 08:56:13 immpc17 kernel: NFS: should not happen in nfs_xdr_readdirres!
Can someone please explain these boot messages:
autoprobing (not recommended) for a single card.

A couple of Oops, this one crashed a bash and left xterm hanging:
