I got the following when trying to mount a particular DVD-R on Linux 2.6.0-test11, using an IDE DVD-RW drive, using SCSI emulation, with the preempt kernel option enabled, and taskfile I/O: (the middle bit was repeated several times):
ide-scsi: reset called for 133 bad: scheduling while atomic! Call Trace: [<c0119acc>] schedule+0x55c/0x570 [<c01259ce>] schedule_timeout+0x5e/0xb0 [<c0125960>] process_timeout+0x0/0x10 [<c02add47>] idescsi_reset+0xf7/0x110 [<c02a7b82>] scsi_try_bus_device_reset+0x52/0x90 [<c02a7c1d>] scsi_eh_bus_device_reset+0x5d/0xe0 [<c02a8368>] scsi_eh_ready_devs+0x28/0x70 [<c02a84ef>] scsi_unjam_host+0xbf/0xd0 [<c02a85da>] scsi_error_handler+0xda/0x120 [<c02a8500>] scsi_error_handler+0x0/0x120 [<c0107329>] kernel_thread_helper+0x5/0xc
SCSI error: host 0 id 0 lun 0 return code = 6000000 Sense class 0, sense error 0, extended sense 0 mount: No medium found
I also suspect that it is refusing to read valid DVD-Rs, but it could just be my drive. One of them successfully mounted and then complained about attempt to access beyond end of device, and another 6 or so refused to mount for the same reason.
If you require any further information, please ask me.
Software: Kernel 2.6.0-test11, configured as above, Debian sid current (glibc2.3 IIRC), mount version 2.12, athlon XP 2800+, ATI's fglrx module loaded, sound (emu10k1) as moule, AGP, and some networking and lm_sensors stuff (all from stock kernel). -- Matthew J Toseland - toad@amphibian.dyndns.org Freenet Project Official Codemonkey - http://freenetproject.org/ ICTHUS - Nothing is impossible.
