Looking at all the emails here, it appears to be really confused.
1. The K StrongARM bug refers to the stm ^ with svc & user registers,
and a certain cache state.
This occurs very frequently if you use the instruction, and causes
Linux to lock solid. This has been solved a long long time ago
(about 3 years ago) in both Linux 2.0 kernels and ARM *BSD kernels.
2. Suspected bug causing random SIGSEGVs. I now believe this not to
be a processor related bug, but some rare events which happen to
co-incide in the kernel (now fixed in 2.2.13, hopefully, if I can
have any feedback, please?).
Hence, for the last 3 years, there have been no additional fixes for
confirmed StrongARM processor bugs in the ARM Linux kernel.
