I'm sorry, but that also generated a panic, looking identical to the
behaviour as for the unpatched 2.6.30-rc6.
After booting the patched kernel, the syslog file showed:
hdc: UDMA/66 mode selected
"hdparm -I" reported that the drive was set to "udma4". On accessing the DVD,
the kernel panicked. Here's the main output from netconsole:
hdc: cdrom_decode_status: error=0x40 <3>{ LastFailedSense=0x04 }
ide: failed opcode was: unknown
hdc: DMA disabled
------------[ cut here ]------------
kernel BUG at drivers/ide/ide-io.c:872!
invalid opcode: 0000 [#1]
last sysfs file: /sys/devices/pci0000:00/0000:00:1f.1/ide1/1.0/block/hdc/size
After booting the kernel and before doing the test I had checked with
"uname -a" that this really was the newly compiled kernel. After reboot I
checked that ide-iops.o existed and had a modification time later than the
moment I applied your patch. Also, the new vmlinuz is 64 bytes shorter than
the unpatched one. Therefore I don't think I made some silly mistake which
led to the patch being ignored.
The offer for testing patches remains open :-).
