Hi guys!
Yesterday I encountered the following bug in my 2.4.20 kernel. My
machine froze (not instaneously, but disk reads didn't work; I had to
hard resetmy machine), and the following entries were written to syslog:

This is an Athlon 1800+, 256MB memory, SiS mobo, IDE (SiS 5513), scsi
(advansys), running 2.4.20 with the 20021212-2.4.20 acpi patch from
acpi.sf.net. The machine has nfs utils version 1.0.2 installed (Debian
unstable) and is running nfs-kernel-server. There were nfs-mounted
disks from a client that was also running Debian unstable with nfs utils
1.0.2. The mount options were rsize=3D8192,wsize=3D8192,nfsvers=3D3,bg,int=
r.
The NFS-related lines from my .config are:
CONFIG_NFS_FS=3Dm
CONFIG_NFS_V3=3Dy
# CONFIG_ROOT_NFS is not set
CONFIG_NFSD=3Dm
CONFIG_NFSD_V3=3Dy
CONFIG_NFSD_TCP=3Dy
CONFIG_SUNRPC=3Dm
CONFIG_LOCKD=3Dm
CONFIG_LOCKD_V4=3Dy
I hope this is any help to you.
