Hello:
i install 8.1 at hp lc2000 yesterday. and i found that hp lc2000
is mandrake 8.1 "certified hardware". there are less than 30 servers
that are "certified hardware". so i think it should work well with MDK.
but the OSB4 DMA bug is there,too. when read a scrateched cd, message
below appear endless:
hda: irq timeout: status = 0xd0 {Busy}
hda: ATAPI reset complete
i can not kill the process which access the cd, can not eject the cd,
the only way to get my cdrom back is reboot.
and when start X 4.1.0, syslog tell me "your processor didn't support
mtrr write-combining". like the 8.2 behavior.
and with mandrake 8.1 i don't see any irq conflict, the system
seems stable. i run ctcs for 18 hours, and no error message.
Regards,
tbsky
