Summary0002623: ide=nodma causes a kernel panic
DescriptionI'm running an x86_64 system with kernel 2.6.18-53.el5. /dev/hda (the only mass storage device) is an ATA adapter for a SD flash card, I suspect that it's bridged from a SATA controller on the motherboard.

When DMA is enabled the machine usually hangs, if it doesn't hang then eventually the kernel resets the interface with DMA turned off. If I have the first line of /etc/rc.sysinit be "hdparm -c1 -d0 /dev/hda" then everything works well. If I try to use "ide=nodma" on the kernel command line then I get the following during the boot process:
