SubjectRe: [patch] stime/settimeofday/adjtimex SMP races (2.2.12 and2.3.18ac5)
The patch applied was mingos timersync-2.2.10-A2 patch! A test run with
Andrea´s patch applied on a 2.2.12 kernel is on the way. I´ll report if
any problems are occuring. Both tests are without running xntpd,
because my machine crashed twice on Saturday (kernel 2.2.3, no oopses
displayed, no xntpd running) and I want to know wheter it is hardware or
it is really an smp race in the kernel.

Running ksymoops on the previous reported oops-message produces the
following output:

Using `/usr/src/linux/System.map' to map addresses to symbols.
