The following reply was made to PR kern/91408; it has been noted by GNATS. From: Eugene Grosbein <eugen@grosbein.pp.ru> To: bug-followup@freebsd.org Cc: jhb@freebsd.org, lightsquid@logvinov.com Subject: Re: kern/91408 : [irq] ata(4) failure: SETFEATURES SET TRANSFER MODE semaphore timeout !! DANGER Will Robinson !! Date: Sat, 29 Apr 2006 23:41:58 +0800 Hi! With 6.1-RC of today I have the same sympthoms as with 5.4-RELEASE (http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/80815): 1) machine suffers from ATA timeouts if ACPI is fully enabled; 2) debug.acpi.disable="pci_link" in /boot/loader.conf eliminates the problem. So, Soren seems to be right: this is interrupt routing problem and not ATA problem. The question is: should I consider the workaround mentioned above as solution? What will I miss if I keep debug.acpi.disable="pci_link" forever? http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/91408 Eugene Grosbein
