as I wrote in letter from 23 Aug 1999,
I'm experiencing kernel oops with 2.3
kernels. I switched to 2.3 at 2.3.14
so I don't know at which time it has been broken.
The thing is that any acces to UMSDOS fs
ends with kernel oops.
Please help me, and not just ignore like the last time... 8(
Here is ksymooped report:
