After updating my CD/DVD drive's firmware to a newer version, I rebooted my system to test the device. I successfully mounted and unmounted a DVD that was formatted with UDF; yet I got this badness message on 2.6.0-test9-mm2:
cdrom: open failed. UDF-fs INFO UDF 0.9.7 (2002/11/15) Mounting volume 'ROBIN_WILLIAMS_LIVE_ON_BROADWA', timestamp 2003/01/06 17:46 (1000) arq->state 4 Badness in as_put_request at drivers/block/as-iosched.c:1783 Call Trace: [<c0290d01>] as_put_request+0x62/0xc0 [<c02869f4>] elv_put_request+0x1f/0x21 [<c02899f1>] __blk_put_request+0x6d/0xb5 [<c0289acf>] blk_put_request+0x96/0x1ab [<c028e048>] scsi_cmd_ioctl+0x23a/0x59a [<c0157294>] kmem_cache_alloc+0xe2/0x1fd [<c02a9b31>] ide_cdrom_check_media_change_real+0x35/0x51 [<c02afc11>] media_changed+0x60/0x87 [<c02afc6d>] cdrom_media_changed+0x35/0x37 [<c02a19fa>] generic_ide_ioctl+0x936/0x9e0 [<c02aa9cb>] idecd_open+0x69/0x8c [<c01851aa>] do_open+0x247/0x70a [<c018469c>] bd_acquire+0x1b7/0x3fd [<c0178d86>] get_empty_filp+0x4f/0xe8 [<c01856ed>] blkdev_open+0x0/0x78 [<c0185721>] blkdev_open+0x34/0x78 [<c02aaa52>] idecd_ioctl+0x35/0x6c [<c028bd6d>] blkdev_ioctl+0xa5/0x449 [<c0192d72>] sys_ioctl+0x204/0x3ee [<c0176eab>] sys_open+0x7e/0x8b [<c03b8cd6>] sysenter_past_esp+0x43/0x65
This is what the IDE subsystem has to say:
Uniform Multi-Platform E-IDE driver Revision: 7.00alpha2 ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx ICH3M: IDE controller at PCI slot 0000:00:1f.1 PCI: Enabling device 0000:00:1f.1 (0005 -> 0007) ICH3M: chipset revision 2 ICH3M: not 100% native mode: will probe irqs later ide0: BM-DMA at 0x1860-0x1867, BIOS settings: hda:DMA, hdb:pio ide1: BM-DMA at 0x1868-0x186f, BIOS settings: hdc:DMA, hdd:pio hda: IC25N030ATCS04-0, ATA DISK drive Using anticipatory io scheduler ide0 at 0x1f0-0x1f7,0x3f6 on irq 14 hdc: HL-DT-STCD-RW/DVD DRIVE GCC-4240N, ATAPI CD/DVD-ROM drive ide1 at 0x170-0x177,0x376 on irq 15 hda: max request size: 128KiB hda: 58605120 sectors (30005 MB) w/1768KiB Cache, CHS=58140/16/63, UDMA(100) hda: hda1 hda2 < hda5 hda6 hda7 hda8 hda9 hda10 hda11 hda12 > hdc: ATAPI 24X DVD-ROM CD-R/RW drive, 2048kB Cache, UDMA(33) And this is what hdparm says about my CD drive:
/dev/hdc: HDIO_GET_MULTCOUNT failed: Invalid argument IO_support = 1 (32-bit) unmaskirq = 1 (on) using_dma = 1 (on) keepsettings = 0 (off) readonly = 1 (on) readahead = 256 (on) HDIO_GETGEO failed: Invalid argument
Should I try fiddling with my hdparm settings, or is it related to the firmware update?
