It looks like a problem I've with every uml-Patch after 24-1um.
After some load/time it freezes/crashes.
That can happen when the clock on the host goes forward / backward (for instance NTP) .... it was reported and discussed, and solved in 2.4.26-3um.
I'd the problem with 2.4.27-1bs too, if I remember corectly.
I'll go and test it:
First: all tests are run on a 2.4.27 with Skas 2.4.25v5 (which includes sysemu)
First I'm goin to try Jeff 2.4.27-1 on a 2.4.29-rc1 (I'd had .28 before, but not run gdb, as I do this time)
Inside the uml I was compiling a kernel.
the .config of the runnig uml is attached (config-27-1jd_on_2.4.29-rc1)
the gdb-Output:
