I recently installed an old Quantum bigfoot drive (CY4320A) in my SMP box running 4.6.2 just to get a little extra space. If I write heavily to it when using WDMA2, the box silently crashes (no panic, just a silent reboot). The box has an DFI motherboard with an Intel BX chipset.
It seems similar to problems others have had with this drive (or maybe the combination of this drive and the PIIX4 controller). From the linux-kernel mailing list: http://groups.google.com/groups?hl=en&lr=&ie=UTF-8&th=efa3cf2a3a198ae0&seekm=fa.l5mj6dv.i2akim%40ifi.uio.no and also with freebsd (though this guy did not actually suffer a crash): http://www.freebsd.org/cgi/getmsg.cgi?fetch=17576+23166+/usr/local/www/db/text/1999/freebsd-current/19990214.freebsd-current I did run across a Compaq "patch" for windows 95 and this drive that says it detects the problem and turns off DMA if it happens... It seems to work okay in PIO4 mode. Are there any possible solutions, or am I just stuck with PIO on this drive? I didn't see any commits to the ata code since 4.6.2 whose log message look like they might workaround this problem. thanks, andrew To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message
