    Host OS Freeze on VMware Server v1.03, Fedora Core 6, X86_64, kernel 2.6.20

    Richard Dale Lurker

      Hi everyone,


      I had a perfectly stable system running on Fedora Core 6, on X86_64, kernel 2.6.18-1.2798 with VMWare Server v1.02 and a Windows 2000 32 bit guest.


      Then I performed an upgrade to kernel 2.6.20-1.2948, VMWare Server v1.03 (and the vmware-any-any-update110 to make the kernel modules compile). 


      Symptoms were that it would run fine for about 10-12 hours then pretty much any command that required disk IO would freeze.  i.e. a logged in SSH session would respond to some simple commands (eg. uptime, ps -eaf) but wouldn't allow much else (ls -l, top etc.).  It appeared that the host OS clock had completely stopped.  The only way to recover was via a shutdown -r (if it worked) or a hard reset.


      Unfortunately nothing to note in dmesg or /var/log/messages (probably since the IO had also frozen too).


      This has happened three days running so I've now had to revert back to 2.6.18 with vmware 1.03 and the any-any-update110 which appears to be stable again.


      So I think there's some bad interaction between the 2.6.20 kernel and vmware server v1.03, at least on Fedora Core 6.
