@SpinningAround I tried your work-around by adding the "all_generic_ide" to the kernel options and it works!!
So far the good news. Although I can now boot with the latest kernel, the solution has a negative impact on disk performance: ------------- With "all_generic_ide" (kernel: 2.6.27-8-generic): >> hdparm -tT /dev/md1 /dev/md1: Timing cached reads: 1768 MB in 2.00 seconds = 884.18 MB/sec Timing buffered disk reads: 54 MB in 3.06 seconds = 17.66 MB/sec Without "all_generic_ide" (kernel: 2.6.27-4-generic): >> hdparm -tT /dev/md1 /dev/md1: Timing cached reads: 1852 MB in 2.00 seconds = 926.06 MB/sec Timing buffered disk reads: 318 MB in 3.00 seconds = 105.84 MB/sec -------------- As you can see the buffered disk reads goes down from 105.84 MB/sec to 17.66 MB/sec on my Raid-0 disk array. So thanks for supplying us with a work-around, but for the longer term we need an actual fix. Regards, Marcel PS.
