    Greetings.

    I have a new VA system and loaded 2.2.17pre. When I
    try to access directories or some files from my
    very stable NFS server, my system hangs hard.
    The server is RH 5.0 with patches to 5.2, 2.0.33,
    uptime 450+ days. Following the hang, I have
    no mouse, no keyboard, no magic sys req keys, etc.
    This seems to be similar to a problem I was
    having with earlier 2.2.x kernels (x=5-12) --
    maybe last fall (seemed to be NFS related).

    I know the old server's NFS is sort of broken,
    but it is very stable. Use of it should not
    hang my workstation.

    Workstation system info:
      brand new VA system with dual PIII/800, 256MB RAM
      ATAPI CD-ROM, UDMA 20G HD, EEPRO 100 10/100 NIC
      Adaptec 8945 (aic7xxx SCSI used only)
      SCSI CD-R and SCSI HD
      Matrox G400 video
      ATI-TV BT848 video card (xawtv works well)
      Sound blaster ES1371 (PCI 128)
      SOund blaster Vibra 16 (ISA, default addresses)

      VA's version of RH 6.2, no patches applied
      2.2.16 with 2.2.17pre15 or 16 patch applied

    The kernel seems to hang sometimes when I access
    large files from my server. X is always running.
    It seems to hang with and without modules loaded
    for video and the SB Vibra 16.

    So far, I have had 3-4 lockups on pre15 and
    one on pre16.

    Alt sysreq keys do not function....

    Any help would be most appreciated. For now, I'm
    trying 2.2.16 stock to see if it has similar
    problems.

    Cheers,
