Reading through my mail logs, I know a board, either FIC PA-2011 or FIC PA-2007 (I seem to have changed my mind somewhere in history) with a 6.4G Quantum Fireball ST, 64MB RAM and an AMD K6-233. The chipset reports as VIA VP2/97; sorry, I do not have access to get the PCI IDs. It locks up with DMA enabled, typically after a few hours, and has done that since 2.1 kernel days. Unfortunately it locks up with Mandrake 7.2 which is not very old (based on 2.2.17 kernels -- it's not my PC any more but I installed Mandrake on it recently). Kernel option "ide=nodma" fixes this -- no lockups. After that "hdparm -X34 -d1" enables DMA and the board remains reliable. I observed one lockup in several years, while X was starting so it could have been X. -X34 does not change the results of "hdparm -t". Note that "hdparm -X34 -d1" enables old DMA, not UDMA. (The board was advertised as UDMA capable but it isn't AFAIK). enjoy, -- Jamie - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org Please read the FAQ at http://www.tux.org/lkml/
