I have been seeing an odd lockup in my linux VM setup. I'm running multiple
linux VMs that are all reading a writing to a shared dasd, and communicating
via CTC. The five linux VMs in my setup are all running SLES7 with SMP timer
patched kernels. They have two virtual processors and 128 MB of memory. When the
machines were running 2.4.7-SuSE-53 kernels, occasionally a machine would hang
completely until I gave it some sort of interrupt (start a 3270 session, and
hit enter). Then it would keep right on going as though nothing had happened
and no time had passed ('date' would return the incorrect time). I heard that
there was a DASD driver bug that was causing this and it was "essentially
eliminated" in the latest patch set from SuSE. Now, I'm running on
2.4.7-SuSE-66 kernels, and I'm still seeing the machines hang. But now they
come back by themselves after an hour or so.
Has anyone else experienced anything like this? Does anyone know if there are
any known bugs in the DASD driver code that could cause something like this?
Thanks in advance
