RE: [linux-sh:01865] [linuxsh-dev] 2.4.7 unaligned user space access problems

[Dustin M. <du...@se...>]

I've tried the new patch, but I'm still getting unaligned access faults.
The faults seem to be generated in somewhat random locations within the
bootup.  I don't know if 'stale' cache information is causing this, but it
would explain the randomness of the errors.  I'll back up to 2.4.6 and look
for these faults.

Dustin.

access problems


I've tested some kernels.  My conclusion is: either CqREEK is broken
or kernel is broken.

Folks, please test the current CVS version and if you have time test
stock 2.4.6 kernel.  Then, please let me know it works well or not.
