IT8212 IDE Controller driver breaks boot on > 2.6.9 FC2 and FC3

From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5) Gecko/20041114 Firefox/1.0 Description of problem: Kernels after 2.6.9-1.667 are built with CONFIG_BLK_DEV_IT8212=y, which includes a new driver for the ITE 8212 IDE/RAID controller chipsets from the -ac patchset. I have one of these controllers (the non-raid variant), and both the most recent FC2 and FC3 errata kernels refuse to boot (kernel panic - no init found). However, I've built a stand-alone module against 2.6.8-1.521 using the source from one of the -ac patches (not sure which one, the version of the driver is 'Version 0.03se October 2004'), which works fine, both inside the initrd and if I insert it after booting. lspci -vv: 00:0e.0 Unknown mass storage controller: Integrated Technology Express, Inc.

FC2 / is on hdc2, FC3 / is on hda8. On the ITE controller I have two cd-roms, hde and hdg. A longshot guess would be that the numbering of the IDE devices got mixed up somewhere between my good version and the errata/FC3 kernels? Version-Release number of selected component (if applicable): 2.6.9-1.6_FC2 How reproducible: Always Steps to Reproduce: 1. Install FC3 with vanilla kernel, or FC2 with latest errata 2. Boot 3. Actual Results: Boot failed, kernel panic - no init found Expected Results: Should boot fine Additional info: This bug should probably be assigned to Alan Cox, since he's written the driver in question.
Alan, sound familiar ? Fixed in latest -ac ?
Never seen this happening and I run FC3/FC2 on IT8212 as you can imagine. The newer it8212 code has fixed various oddments but there is nothing IDE fixed that would impact this since the pci/generic fix to sort out stealing SATA adapters. I can't see it being ordering because the newer initrd stuff we have is all based on LABELs so it would find the root fs wherever it hid
Actually, it turns out my guess was right. The onboard IDE channels are now hd[e,f,g,h] and the ITE board channels are hd[a,b,c,d]. This broke grub and fstab, since they both use /dev/hdX notation (custom modification of mine though). It should work fine if grub/fstab are using labels. Remind me again, how do I edit the partition labels? I can't find anything relevant in fdisk.
tune2fs I think. You may also need to reinstall grub to get the boot blocks right. Will close this now we know it isnt a kernel bug per se.
