Hello,
I have two problems with JFFS2 now.
The first problem appears if SMP is enabled. I described is in the mtd-list.
The second one is the CRC errors. I also mentioned it
I've installed 4 variants of the Linux-2.6.8.1 kernel on my i686 test host:
1. SMP, Preemption
2. SMP, No preemption
3. UP, Preemption
4. UP, No preemption
I've testes JFFS2 on all these configurations and have observed:
The first problem appears only on configurations 1 and 2.
The second problem appears only on configuration 1 and 3
The configuration number 4 has no problems.
So I may suppose that:
1. The first problem is SMP-related.
2. The second problem is preemption-related.
3. Both problems relate to race conditions.
Comments?
