2.6.11-rc[1,2]-mmX scsi cdrom problem, 2.6.10-mm2 ok

[Fabio Coatti <cova@ferrara.linux.it>]

I'm seeing a problem with latest mm releases; with 2.6.11-rc1,2-mmX every time 
I fire up k3b, it get stuck here: (last line, previous lines just for 
documentation :) )

open("/dev/hdc", O_RDONLY|O_NONBLOCK)   = 11
ioctl(11, CDROM_SEND_PACKET, 0xbfffc4e0) = 0
close(11)                               = 0
open("/dev/hdc", O_RDONLY|O_NONBLOCK)   = 11
ioctl(11, CDROM_SEND_PACKET, 0xbfffc590) = -1 EIO (Input/output error)
close(11)                               = 0
open("/dev/hdc", O_RDONLY|O_NONBLOCK)   = 11
ioctl(11, CDROM_SEND_PACKET, 0xbfffc4e0) = 0
ioctl(11, CDROM_SEND_PACKET, 0xbfffc4e0) = 0
close(11)                               = 0
open("/dev/hdc", O_RDONLY|O_NONBLOCK)   = 11
ioctl(11, CDROM_GET_CAPABILITY or SNDRV_SEQ_IOCTL_UNSUBSCRIBE_PORT, 
0x7fffffff) = 3735535
close(11)                               = 0
lstat64("/dev", {st_mode=S_IFDIR|S_ISVTX|0777, st_size=30220, ...}) = 0
lstat64("/dev/sr1", {st_mode=S_IFBLK|0600, st_rdev=makedev(11, 1), ...}) = 0
open("/dev/sr1", O_RDONLY|O_NONBLOCK)   = 11
fstat64(11, {st_mode=S_IFBLK|0600, st_rdev=makedev(11, 1), ...}) = 0
ioctl(11, CDROM_SEND_PACKET, 0xbfffd740) = 0
close(11)                               = 0
open("/dev/sr1", O_RDONLY|O_NONBLOCK)   = 11
fstat64(11, {st_mode=S_IFBLK|0600, st_rdev=makedev(11, 1), ...}) = 0
ioctl(11, CDROMAUDIOBUFSIZ or SCSI_IOCTL_GET_IDLUN, 0xbfffd7e8) = 0
ioctl(11, SCSI_IOCTL_GET_BUS_NUMBER, 0xbfffd8a4) = 0
close(11)                               = 0
open("/dev/sr1", O_RDONLY|O_NONBLOCK)   = 11
ioctl(11, CDROM_SEND_PACKET, 0xbfffd7d0) = 0
ioctl(11, CDROM_SEND_PACKET          

At this point k3b is stuck in D stat, needs reboot.

I've thinked of faulty HW, but 2.6.10-mm2 can complete the scan (I haven't 
tried to use that device, to ber honest, after successful initialization).

On scsi- bus I've the following devices:
cova@kefk ~ $ cat /proc/scsi/scsi

Let me know if further details/testing are needed.
