Just in case someone is not reading linux-sparc, I'm reposting this small patch. After this patch my SS20 boots 2.2.7 kernel and seems to be stable.
From: Pete Zaitcev <[EMAIL PROTECTED]> Subject: [PATCH] oneliner in iommu.c To: [email protected] Date: Thu, 6 May 1999 22:43:08 -0700 (PDT) JavaStation-1 hangs (loops) when bank 0 has 32MB and bank 1 has 8MB. It turned out that when we insert the element into the sorted list we also append it, and this makes a circular list. Index: arch/sparc/mm/iommu.c --- arch/sparc/mm/iommu.c 1998/04/15 14:58:37 1.9 +++ arch/sparc/mm/iommu.c 1999/05/07 05:32:04 @@ -118,6 +119,7 @@ if (ia[i].addr <= ia[l].addr) { ia[i].next = l; ia[m].next = i; + break; } if (l == -1) ia[m].next = i; What puzzles me is that 2.2.5 has exactly the same bug, but it works. Anyone saw unusual behaviour on sun4m's recently? --Pete
