- Hello fellow kernel hackers,
-
- Well if you are unfamiliar with my troubles I will relate them to you:
-
- I have had problems with certain prgrams, `gas' and `emacs' to name a
- few, what the problems are are hard to describe but take my word
- they look like intermitent memory trashing problems--even more so like
- stack but I can't be sure on this one.
-
- Happy news is I have discovered a way to remove them, I boot without
- my 16 bit ram.
-
- Isn't that nice :^) Nice and nasty is about all. So I am reporting
- to you that for some reason the kernel or user programs (my intuition
- leans more towards the kernel) Is messing up somehow with 16 bit ram.
-
- My system is odd becuase I have 4M of 32 bit at 0x200000 and then 2M
- of 16 bit at 0x600000 and another 2M at 0x800000. I can run mergemem
- to make them look like a single large contiguous chunk or not and then
- netbsd uses the first 4M of 32 bit only.
-
- My first and best guess doesn't appear to be correct, I thought maybe
- the ram was being used for the kernel *and* for GVP bounce buffers but
- my kernel had use_z2_mem set to zero, so thats not what was happening.
-
- I have:
- 4M on GVP 030/22
- 2M on GVP series I
- 2M on supra ram card.
- 1M chip. ECS chipset A2000.
-
- Its not as very important to me now to get them fixed as I can now buy
- some more GVP ram and continue to develop for NetBSD.
-
- It should probably get loked into though.
-
- Any quick guesses?
-
- Chris.
