I initially added only the two quantum drives to the pdc_quirk_list, and that had no effect, the machine still hung on boot up at the same place. After this, I added the other two Maxtor's as well, and with all four drives in the pdc_quirk_list, the system booted up fine.
Should I narrow this down further? Will it be detrimental in any way to have all four drives listed in the quirks table if they needn't be?
cat /proc/ide/pdc: PDC20262 Chipset. ---------------------------- General Status --------------------------------- Burst Mode : enabled Host Mode : Normal Bus Clocking : 33 PCI Internal IO pad select : 4 mA Status Polling Period : 0 Interrupt Check Status Polling Delay : 0 ------------ Primary Channel ---------------- Secondary Channel ------------- enabled enabled 66 Clocking enabled enabled Mode PCI Mode PCI FIFO Empty FIFO Empty ------------ drive0 --------- drive1 -------- drive0 ---------- drive1 ------ DMA enabled: yes yes yes yes DMA Mode: UDMA 4 UDMA 4 UDMA 4 UDMA 4 PIO Mode: PIO 4 PIO 4 PIO 4 PIO 4
and hdparm yields about 25Mbit/s.
I'm trying to get the runtime system to hang like it did before as well... I'm running "dd if=/dev/hdX of=/dev/null &" on all four drives simultaneously, and about 3 times per drive to hit the controller and disk I/O system really hard. So far, it's all been fine. Hopefully that means that the problems gone away. :)
Thanks for the help!
