I have just updated my system to an AMD K6/233. Chip serial number is
"C 9818 FPJW". And, of course, my OS is FreeBSD 2.2.6-RELEASE.
Some other details on my setup:
Mobo: EFA E5TX-AT-5 "Pegasus I"
Chipset: Intel 430TX (Triton); MTXC (82439TX)*1, PIIX4 (82371AB)* 1; I/O
chipset is ALI M5135 (Yes, I am using the IWill sio patches...)
OS: FreeBSD 2.2.6-RELEASE, with the IWill sio patches.
I heard a while back about serious problems with the K6, so I searched the
mailing list archives. There were indeed problems, but AMD reportedly
fixed them as of chip revision "B 9729 xxxx". Since I have heard no new
problem reports since then, I am assuming my chip is one of the "good"
revisions.
Anyway, the system appears to be working fine and all, that is, for normal
usage. However, the other day I tried a "make world" on the 2.2.6-RELEASE
sources, and got an error. Which leads into...
1. Make world fails at *exactly* the same file, with *exactly* the same
error.
I've run three consecutive 'make world's, and all of them fail, but they
fail at *exactly* the same file, with *exactly* the same error. Here is
the log from one such session:

Failed assertion at line 161, file

.
Abort trap - core dumped
*** Error code 134
In all cases, the "refer" process dies with signal 6, according to the
system logs (dmesg).
Since the problem occurs at exactly the same spot, with exactly the same
error, I am leaning towards suspecting a problem on my installed system,
rather than a hardware problem (since hardware trouble generally produces
random, unpredictable errors).
And, speaking of system crashes...
2. Odd system crash -- once.
When I said before that "the system appears to be working fine and all,"
that was sort of a lie. The system did crash, *ONCE*. I have *NOT* been
able to reproeduce this crash, however.
What happened is this: I was in X, doing a *LOT* of things simultaneously
(i.e. the system was heavily loaded) -- a bunch of usenet articles were
being spooled in, I was running a make world, encoding some mp3's, the
usual Netscape and email client, etc. Then I started up XV to view some
graphics that just came in. The system froze, and rebooted. The system
did dump core, however, and this is the result (using kgdb):
IdlePTD 279000
current pcb at 25325c
panic: vref used where vget required
#0 0xf0116c5e in boot ()
(kgdb) bt
#0 0xf0116c5e in boot ()
#1 0xf0116f4a in panic ()
#2 0xf013cc07 in vref ()
#3 0xf01043d0 in iso_iget ()
#4 0xf010686a in cd9660_root ()
#5 0xf013b6c0 in lookup ()
#6 0xf013b04d in namei ()
#7 0xf013fa04 in stat ()
#8 0xf01f59a6 in syscall ()
#9 0x2fc5 in ?? ()
#10 0x107e in ?? ()
Again, I have not been able to reproduce this. I've run the system
ragged since then, and it hasn't crashed a single time.
Now, last, but not least, I have a not-so-serious (but cosmetically
ugly) problem:
3. Dmesg output is slightly screwy.
If I boot tje GENERIC kernel, the CPU type is properly detected and prints
out properly:
CPU: AMD-K6tm w/ multimedia extensions (233.86-MHz 586-class CPU)
Origin = "AuthenticAMD" Id = 0x562 Stepping=2
Features=0x8001bf<FPU,VME,DE,PSE,TSC,MSR,MCE,CX8,MMX>
however, if I boot my own custom kernel, it shows something really odd.
CPU: \^E (233.86-MHz 586-class CPU)
Origin = "AuthenticAMD" Id = 0x562 Stepping=2
Features=0x8001bf<FPU,VME,DE,PSE,TSC,MSR,MCE,CX8,MMX>
Note the odd-looking CPU name...
Perhaps I'm doing something slightly wrong in my config? A copy of it is
attached for your viewing pleasure.
Anyway, your input is greatly appreciated. Thanks in advance!
