I started having process hangs with a kernel built from sources on 3/14 so I supped sources on 3/15 and built a kernel with no lkm's. Now I get consistent page fault panics and sometimes multiple free panics. I went back to lkm's with the same results. The only source difference is the changes David made to uipc_mbuf.c and the SCSI sense code messages. Another difference in my system is that I inadvertently did a make install in gnu/usr.bin/cc so I now have gcc-2.6.3. When I realised my mistake I also installed the new loaded and assembler. Is there a problem compiling kernels with 2.6.3? Here is a typical panic. Fatal trap 12: page fault while in kernel mode fault virtual address = 0xeff83718 fault code = supervisor read, page not present instruction pointer = 0x8:0xf0701aa6 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = 69 (named) interrupt mask = panic: page fault The task is always named or ppp but most of the time named. The instruction pointers make no sense, they are not in the symbol table. The fault address is all over the place too, sometimes 0. I re-supped the entire sys tree in case something was out of sync but there were no differences. John Capo
