Hi, I have an up-to-date FreeBSD 4-STABLE system with onboard ATA controller (VIA 82C586-mumble) but no ATA/ATAPI devices (SCSI only). I tried putting disable ata disable ata0 disable ata1 quit into /boot/kernel.conf to skip probing these devices (it hangs until timeout), but to no avail, the kernel still sees ata0 and ata1 and probes for drives (which takes several dozen seconds). I see at boot-up that these disable instructions are executed (the corresponding loader.conf flag is set). I also tried disabling atapci0 which is what I see, but that one is rejected with something like "no such device". Is this a known issue or should I file a PR? TIA, -- Matthias Andree

This BUG is very strong and don't resolve in kernel.conf. I wrote about this 3 times, but Soren Schmidt <sos@FreeBSD.org> is very busy for resolving this problem more than 1 year or don't read stable@ and e-mail. -- Vladislav V.
