Re: safe mode for kernel.old
Then what's the safe mode in the boot screen in 5.2.1, and how is it different than single user mode? Thanks for your patience with me on this issue. AFAIK, among others doesn't set DMA disk access. syctl: hw.ata.ata_dma=0 hw.ata.atapi_dma=0 This seems to have fixed the problem, it must have been a DMA conflict in some way.

RE: safe mode for kernel.old
I think you have missed some very important details. In 4.x releases when you do a kernel compile the system automatically renames the current kernel to kernel.old for you. There is also a kernel.generic which is always there. In 5.x versions the whole kernel boot process was replaced with new method and the auto rename of the kernel no longer happens on a recompile and there is no kernel.generic module available. Whoever added the new boot process to 5.x did real poor job of integrating the new pirated boot code into Freebsd. This should be reported as a bug by everybody who wants the old kernel rename process added back into FreeBSD.

RE: safe mode for kernel.old
You used the upgrade in place from source so the old kernel release version was left over by error. Try doing an separate stand alone kernel recompile and the kernel.old is not created. This problem is more visible for people who install 5.x from scratch. Or maybe this is a difference between using the new buildkernal process over the older kernel compile process. All I know for sure is I installed 5.2.1 from miniistall.iso install CD and used the older kernel compile process to build a custom kernel and the kernel.old module was not created and the kernel.generic module was never there. So what I am saying is you may be trying to run the kernel.old module from 5.1 and not the one you think you built from 5.2.1. -Original Message- From: Bill Moran [mailto:[EMAIL PROTECTED] Sent: Saturday, July 31, 2004 11:01 AM To: [EMAIL PROTECTED] Cc: [EMAIL PROTECTED]; [EMAIL PROTECTED]; [EMAIL PROTECTED] Subject: Re: safe mode for kernel.old JJB [EMAIL PROTECTED] wrote: I think you have missed some very important details.
