I get messages in /var/log/messages about "attempt to access beyond end of device". This happend both with kernel-2.4.18-24.8.0 and 2.4.18-19.8.0. grub.conf has hdc=ide-scsi kernel /vmlinuz-2.4.18-24.8.0 ro root=LABEL=/ hdc=ide-scsi The RDRW mode is: "LG CD-RW CED-8080B" Loaded modules are: /sbin/lsmod Module Size Used by Not tainted sg 36588 0 (autoclean) loop 12152 0 (autoclean) smbfs 43680 2 (autoclean) sr_mod 18168 0 (autoclean) es1371 30760 0 (autoclean) ac97_codec 13416 0 (autoclean) [es1371] gameport 3412 0 (autoclean) [es1371] soundcore 6532 4 (autoclean) [es1371] i810 72736 1 agpgart 43136 7 (autoclean) autofs 13348 0 (autoclean) (unused) eepro100 22264 1 ipt_REJECT 3736 2 (autoclean) iptable_filter 2412 1 (autoclean) ip_tables 15224 2 [ipt_REJECT iptable_filter] ide-scsi 10512 0 scsi_mod 107240 3 [sg sr_mod ide-scsi] ide-cd 33608 0 cdrom 33696 0 [sr_mod ide-cd] mousedev 5524 1 keybdev 2976 0 (unused) hid 22244 0 (unused) input 5920 0 [mousedev keybdev hid] usb-uhci 26188 0 (unused) usbcore 77024 1 [hid usb-uhci] ext3 70336 3 jbd 52212 3 [ext3] --------------------- Error messages ----------- Feb 2 05:35:36 host133 kernel: attempt to access beyond end of device Feb 2 05:35:36 host133 kernel: 0b:00: rw=0, want=34, limit=2 Feb 2 05:35:36 host133 kernel: isofs_read_super: bread failed, dev=0b:00, iso_blknum=16, block=16 Feb 2 05:35:46 host133 kernel: attempt to access beyond end of device Feb 2 05:35:46 host133 kernel: 0b:00: rw=0, want=34, limit=2 Feb 2 05:35:46 host133 kernel: isofs_read_super: bread failed, dev=0b:00, iso_blknum=16, block=16 Feb 2 05:36:14 host133 kernel: attempt to access beyond end of device Feb 2 05:36:14 host133 kernel: 0b:00: rw=0, want=34, limit=2 Feb 2 05:36:14 host133 kernel: isofs_read_super: bread failed, dev=0b:00, iso_blknum=16, block=16 Feb 9 03:30:16 host133 kernel: attempt to access beyond end of device Feb 9 03:30:16 host133 kernel: 0b:00: rw=0, want=34, limit=2 Feb 9 03:30:16 host133 kernel: isofs_read_super: bread failed, dev=0b:00, iso_blknum=16, block=16 Feb 9 03:30:37 host133 kernel: attempt to access beyond end of device Feb 9 03:30:37 host133 kernel: 0b:00: rw=0, want=34, limit=2 Feb 9 03:30:37 host133 kernel: isofs_read_super: bread failed, dev=0b:00, iso_blknum=16, block=16
I guess this is a "Me too" comment. The problem is pretty much the same, though the hardware is quite different: Tyan Tiger MP S2460 2xAMD MP 2400+ CD/RW is on Maxtor (promise OEM 133TX2) 133 controller (hdg) I have to boot with 'noapic' or computer locks-up sporadically.
Upgrading to the rawhide kernel (2.4.20-2.54smp) seems to solve both problems: I can read CDs again and it has not locked up (there is no 'noapic' this time) yet (~20 hours). Sincerely, Dmitri.
