Subject: [2.4.21-pre3] BUG: IDE DMA doesn't work w/ x86 HighMem
Date: Fri, 10 Jan 2003 09:04:39 -0800 [thread overview]
Message-ID: <3E1EFD27.5010008@google.com> (raw)
Configure the 2.4.21-pre3 kernel with IDE and Highmem and when DMA is
attempted you get a BUG from asm-i386/pci.h line 155 called from
drives/ide/ide-dma.c line 282.
From the looks of it, the IDE driver has not been highmem enabled, but
does get a high-mem device queue.
This is easily reproduced on a dual proc P3 with 2 Gigs of ram.
