3 x) An unknown math coprocessor bug. (Ultrix' dxclock sometimes looks
4 weird.)
5
6 x) Enabling cache emulation (./configure --enable-caches) triggers bugs.
7
8 x) Linux/DECstation (Debian) oopses extremely often unless -U is used
9 at run-time. I'm not sure yet why it bugs out. With -U, the risk is
10 lower, but not completely gone. _Maybe_ this is a bug in Linux. Why?
11 Because the oops message contains things like ANSI escape codes and
12 characters in registers (including the pc and return address register);
13 this looks like a buffer overflow in the serial driver. (Another thing
14 that gives weight to this theory is that the serial driver in Linux is
15 still being developed.) But this is just a guess.
16
17 o) Hardware device ticks are done at cycle specific intervals, not
18 instruction intervals, so sometimes a fraction of a cycle can be
19 "lost".
20
21 o) Running Linux/DECstation 2.4.26 with no scsi disks attached causes
22 a warning message to be printed by Linux.
23
24 o) UDP packets that are too large are not handled well by the Lance device.
25
26 o) Colors in X11 framebuffers on MacOS X hosts are wrong. (I'm not sure
27 how to solve this; the code works on both little-endian (Alpha) and
28 big-endian (UltraSPARC) X-servers...)
29
30 o) Binary-translated 64-bit stuff checks to see if the top 32 bits are
31 all zeroes or all ones, and then uses 32-bit tables and such. This
32 is a bug. It should check the top 33 bits, not 32. (Alpha only, already
33 fixed for i386?)
34
35 o) NetBSD/arc 2.0 uses the ASC controller in a way which GXemul cannot yet
36 handle. (NetBSD 1.6.2 works ok.)
