From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.10) Gecko/20050720 Fedora/1.0.6-1.1.fc4 Firefox/1.0.6 Description of problem: i upgraded my ibm thinkpad r30 which has a sony crx700e removable cdrw drive from kernel-2.6.11-1.35_FC3 to kernel-2.6.11-1.1372_FC3 and the computer will not finish booting if the cdrw drive is in the bay. it is an ide cdrw. i get the error: Disabling IRQ #15 ide1 at 0x170-0x177,0x376 on irq 15 hdc: ATAPI 24X CDROM CD-R/RW... hdc: lost interrupt and the computer hangs there. there were no issues with the previous install. i have searched the web extensively and tried boot options like noacpi, acpi=off, acpi_irq_balance, and hdc=ide-scsi. the only boot parameter that allows the computer to continue booting is hdc=ide-scsi, but once i am logged in after using that command, my cdrw is completely inaccessible and does not show up anywhere in the /dev folder. Version-Release number of selected component (if applicable): kernel-2.6.12-1.1372_FC3 How reproducible: Always Steps to Reproduce: 1. install kernel-2.6.12-1.1372_FC3 2. boot using that kernel 3. wait for the computer to give the errors Actual Results: see description Expected Results: computer will boot as normal and cdrw drive will be accessable after booting Additional info: no workaround is present, that's why i've classified the severity as high.
i made a mistake in my previous submission... (i am new at this). if i use acpi=off as a boot option, the system loads just like it used to and i can use the cdrw drive. changing severity to low because this is something that should be detected on kernel upgrade.
This sounds the same as bug 162347
no, this is something else, note the problem here is seen on the latest errata kernel.
IRQ routing not IDE
Can you try the kernel from updates-testing please ?
