If I mount /dev/hd[cd], the system freezes completly.

Please verify that 2.5.42 works correctly, and send me the boot log of such a boot.

Kernel Bug at drivers/ide/ide-cd.c: 860!

Quoted 12 lines · Jens Axboe

I tried 2.5.43 with mixed results. In dmesg i see:
2.5.42 is the one you should test, like I said in the mail.
Quoted 2 lines
But I am still able to mount /dev/hdc and /dev/hdd Hope it helps. Thanx for caring!
So 2.5.43 sort-of works?
