Hi,
I just noticed very unstable ISDN connections since the introduction of
preempted interrupt threads (Jan 31st). Most errors are uncritical though,
an active connection continues to work, sometimes I have to restart isdnd,
and sometimes I even have to reboot the machine.
The "i4b-L1 isic_hscx_waitxfw: HSCX wait for XFW timeout!" seem to have
been introduced by the SMPng code, but with interrupt preemption they
appear more often (I switched th SMPng on Jan 25th)
As you can also see on the output: On Feb 9th I rebooted the machine
with a newly built kernel. All other errors besides the one mentioned
above suddenly disappeared.
A quick look at the change logs revealed: preemption was accidently
removed for interrupt threads on Feb 9th - and reintroduced a few hours
later. It seems I was running such a kernel for a week (Feb 9th - 18th)
Anyone else having the same problem?

Daniel
