Heya :-)

Having a funny showstopper problem here with md, the autostart fails 
miserably with "md: bug in file md.c, line 1440"

Here's the story;

A few weeks ago, when running 2.4.22-pre7, I had to temporarily jank out 
a drive from a two drive md raid 1 setup, a raid1 setup that had been 
working flawlessly for ages.

Then, some days ago, I added the drive back in, as I got it back. I 
raidhotadd'ed the partitions after cloning back the partition table with 
sfdisk. All swell, I though, untill I decided to upgrade kernel to 
2.4.22, wich of course means a reboot.

Reboot, boom. Unable to mount root fs. Tried to boot old 2.4.22-pre7 
kernel again, still boom. Janking the hdc drive again lets it boot 
normally again. Tried adding the hdc drive in another computer and dd 
if=/dev/zero'ed it, moved it back, recreated the partitions manually, 
and hotadded. Same problem, works fine, until I reboot.

minicom dump and raidtab attached, should contain most relevant 
information. If not, yell. The system is running Debian Unstable. Notice 
the kernel command line, hdc has overridden geometry. The two drives are 
identical, still the bios or whatever is giving them away differently. 
The override "had" to be done to get the raid up and running properly.
