The following reply was made to PR kern/60526; it has been noted by GNATS. From: Eugene Grosbein <eugen@kuzbass.ru> To: bug-followup@freebsd.org Cc: sos@freebsd.org, stable@freebsd.org Subject: Re: kern/60526: Post-PAE stable SMP machine freezes Date: Thu, 18 Mar 2004 11:00:09 +0700 Hi! According to http://freebsd.rambler.ru/bsdmail/freebsd-hackers_2003/msg03936.html the problem may be related to the <ServerWorks ROSB4 ATA33 controller> and ATA write cache (hw.ata.wc=1). Note however, I had no kernel panic with post-PAE STABLE. I had kernel lockup. I can understand kernel panic due to the faulty devices but not endless loop that it seems to happen. It's known (and noted in the Errata for 4.9-RELEASE) that PAE integration broke hw.ata.tags. Perhaps, its time either to document that hw.ata.wc is broken for noted controller too, either to forbid write cache for it by force. I run my machine using pre-PAE 4.8-STABLE with security patches still. Eugene Grosbein
