Hi parisc folks, I have noticed that the mainline kernel won't boot any more on my hp712/100, starting with v2.6.39. It panics in flush_instruction_cache_local. After bisection, it appeared the culprit was commit f311847c2fcebd81912e2f0caf8a461dec28db41 "parisc: flush pages through tmpalias space". Reverting it made v2.6.39 boot again. For v3.0, I needed to revert a few more patches simply to allow reverting the original bad commit. And starting with v3.2, I needed to add the patch from John David Anglin to adjust section arrangement, too (see http://www.spinics.net/lists/linux-parisc/msg04091.html). Here is the final patch "pile" I need on v3.4-rc6 to make it boot properly: <patch from John David Anglin> Revert f311847c "parisc: flush pages through tmpalias space" Revert 8b4ae334 "eliminate special FLUSH flag from page table" Revert b54cd0d5 "[PARISC] fix pacache .size with new binutils" Revert b7d45818 "[PARISC] prevent speculative re-read on cache flush" If someone manages to repair the cache routines, I would be glad to test the patches :) Best regards, -- Vincent Stehlé Kernel panic when booting v3.4-rc6 with only the patch from John David Anglin: ...
