I've done some more tests: The problem still occurs with straight ide drivers, no ide-scsi The problem still occurs with 2.4.20-ac2 I removed extraneous llseek syscalls from libdvdread, it's now reading purely sequentially and still failing. I doubt an llseek to the current location even gets through to the driver but I figured I would remove another variable. Question: Does the readahead parameter in hdparm affect accesses to the raw /dev/hdd device? Does it affect atapi cdrom access? -- greg - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
