| |
Ok I did some digging and some mmap runs. Basically in some cases an mmap of a page on a SCSI device does indeed cause the kernel to use more than 4K of kernel stack and crash. I _suspect_ its only just tripping when the kernel stack of the process is quite dead on a page fault during the mmap as its not a simple run this and crash case.
Anyway it is a definite 2.0.x bug. I also cannot duplicate it so far with IDE
