There seem to be the grave bug in that kernel. When either process is trying to access the cdrom, it gets stuck in the kernel forever. Even "eject" locks up. This started to happen somewhere around -mm4 I think. Specifying "pci=routeirq" makes the kernel to deadlock at boot, right after detecting the cdrom. Sometimes there are the "ide1: lost interrupt" messages on console. Attached are the different bits of info I found usefull for that report. It includes the Alt-PrtSc-t trace and the random info about my cdrom. Any suggestions on getting this fixed? This one is really severe I suppose. --------------030007080001060601020107 Content-Type: text/plain; name="trace" Content-Transfer-Encoding: 7bit Content-Disposition: inline; filename="trace" Nov 15 14:21:38 stas kernel: eject D C046C148 2500 3426 3363 (NOTLB) Nov 15 14:21:38 stas kernel: db4c8cc4 00000086 c046c0b8 c046c148 db4c8dd0 db4c8ca4 c0290e9c c0290c90 Nov 15 14:21:38 stas kernel: 00001388 dfce797c c046c0b8 df778028 c046c148 00000000 db4c8cb4 c1405f60 Nov 15 14:21:38 stas kernel: 00068a1b 5a045780 000f420a df9a3c10 db4c8d48 db4c8d44 db4c8000 db4c8d18 Nov 15 14:21:38 stas kernel: Call Trace: Nov 15 14:21:38 stas kernel: [] wait_for_completion+0x94/0x100 Nov 15 14:21:38 stas kernel: [] ide_do_drive_cmd+0x118/0x150 Nov 15 14:21:38 stas kernel: [] cdrom_queue_packet_command+0x44/0xb0 Nov 15 14:21:38 stas kernel: [] cdrom_check_status+0x74/0x90 Nov 15 14:21:39 stas kernel: [] ide_cdrom_check_media_change_real+0x1d/0x40 Nov 15 14:21:39 stas kernel: [] media_changed+0x5a/0x90 Nov 15 14:21:39 stas kernel: [] check_disk_change+0x32/0x80 Nov 15 14:21:39 stas kernel: [] cdrom_open+0x6b/0x100 Nov 15 14:21:39 stas kernel: [] idecd_open+0x5d/0x80 Nov 15 14:21:39 stas kernel: [] do_open+0xe8/0x370 Nov 15 14:21:39 stas kernel: [] blkdev_open+0x28/0x60 Nov 15 14:21:39 stas kernel: [] dentry_open+0x156/0x280 Nov 15 14:21:39 stas kernel: [] filp_open+0x4d/0x50 Nov 15 14:21:39 stas kernel: [] sys_open+0x3c/0xa0 Nov 15 14:21:39 stas kernel: [] sysenter_past_esp+0x52/0x71 --------------030007080001060601020107 Content-Type: text/plain; name="driver" Content-Transfer-Encoding: 7bit Content-Disposition: inline; filename="driver" ide-cdrom version 4.61 --------------030007080001060601020107 Content-Type: text/plain; name="model" Content-Transfer-Encoding: 7bit Content-Disposition: inline; filename="model" ASUS CD-S500/A --------------030007080001060601020107 Content-Type: text/plain; name="piix" Content-Transfer-Encoding: 7bit Content-Disposition: inline; filename="piix" Controller: 0 Intel PIIX4 Ultra 100 Chipset. --------------- Primary Channel ---------------- Secondary Channel ------------- enabled enabled --------------- drive0 --------- drive1 -------- drive0 ---------- drive1 ------ DMA enabled: yes no yes no UDMA enabled: yes no yes no UDMA enabled: 5 X 2 X UDMA DMA PIO --------------030007080001060601020107-- - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
