Public bug reported: This system was recently upgraded to Ubuntu 8.04 (kernel 2.6.24-16-generic). It has three hard drives, two of which are PATA, one SATA. The PATA drives are detected neatly on ata1 and ata2, but the kernel spends a lot of time trying to probe ata3 and ata4 for a drive - and finds nothing. (also, it takes 30 seconds per probe, and tries probing both devices thrice, so these probes add three minutes to the bootup time. I tried passing ata_probe_timeout=5, but it had no effect.).
The dmesg output (attached) seems to indicate that something is wrong with APIC. I've tried booting with irqpoll, pci=noacpi, and noapic+nolapic. None of these options have changed anything as far as I can tell. lspci identifies the controller as: 00:0f.0 IDE interface: VIA Technologies, Inc. VT8251 AHCI/SATA 4-Port Controller 00:0f.1 IDE interface: VIA Technologies, Inc. VT82C586A/B/VT82C686/A/B/VT823x/A/C PIPC Bus Master IDE (rev 07) I plan to "fix" this system for now by downgrading to a kernel that doesn't use libata by default for this chipset, because I suspect this breakage is libata's fault. This isn't my computer, so I mightn't be able to respond to queries about this bug quickly... ** Affects: ubuntu Importance: Undecided Status: New -- Hardy doesn't find SATA drive on VT8251 https://bugs.launchpad.net/bugs/223010 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
