I do not even have IDE Taskfile Access enabled, so how is the kernel printing these error messages before it freezes?
linux-2.6.13/drivers/ide/ide-taskfile.c: printk(KERN_ERR "%s: no DRQ after issuing %sWRITE%s\n",
lqqqqqqqqqqqqqqqqqqqqqqq ATA/ATAPI/MFM/RLL support qqqqqqqqqqqqqqqqqqqqqqqk x x[ ] IDE Taskfile Access
Anyone have any suggestions how I can solve this problem?
