I have just cvsupped and built the latest -current kernel and have noticed
a new quirk plus an old quirk or 2. uname -a output is:
FreeBSD XXXX 4.0-CURRENT FreeBSD 4.0-CURRENT #0: Fri Nov 26 02:06:45 EST
1999 root@pacer.nlc.net.au:/usr/src/sys/compile/PACER i386
1) CMOS clock problem, dmesg output:
"Invalid time in real time clock.
Check and reset the date immediately!"
The system goes to Jan 27 1999 until ntpdate kicks in and fixes it.
However each time I boot the time is bad again. This could be a
hardware glitch although it was perfectly timed to start happening
just as I booted into a newly built kernel...very suspicious.
2) ISA unexpected tag problem, dmesg output:
"pci0: unknown card (vendor=0x121a, dev=0x0001) at 11.0"
"isa0: unexpected tag 14"
The PCI device is a Diamond Monster 3D (3Dfx Voodoo 1). I don't know
if there is a relationship or if it is pue chance that they are
located next to each other. This has been long standing and is not
a recent gremlin, it doesn't seem to affect anything.
3) The new ATA drivers have a display formatting bug that results in the
following output if a CDROM doesn't doesn't supply speed info:
", 512KB buffer, PIO"
Patch is attached with MIME to save tabs and formatting. I think I
sent this to Soren a while ago, although the latest commits from him
didn't fix the problem. Maybe they got lost, as he was very responsive
to a previous patch.
4) My Pioneer DVD drive causes the following:
"atapi: MODE_SENSE_BIG - UNIT ATTENTION skey=6 asc=29 ascq=00 error=00
acd0: <Pioneer DVD-ROM ATAPIModel DVD-103S 0116/E1.16> CDROM drive at
ata1 as slave"
Is the MODE_SENSE_BIG a problem report or a diagnostic output.
Thanks.
