I don't know if this is just G2 flakiness, but if I start playing sound and then start hotplugging devices then I will sometimes get this sort of oops (these don't down the system but they can make it unstable) - any clues as to what might be the issue (these are now quite old -rc2? kernels...)... just wondering if anybody can see anything obvious?

Write-through works fine on all of my 2-way and 4-way set associative dcaches, you're probably the only user of direct-mapped SH caches these days. I'll see if I can dig up a board with a direct-mapped cache or see if this is reproducable with EMODE disabled on 2-way. Does disabling the dcache work for you? |
