This is taking longer than I hoped, so here's a little progress report. On Thu, 3 Apr 2008 16:17:33 -0700, Andrew Morton wrote:

Hardware: Intel Pentium D940, Intel DQ965GF board, two SATA hard disks. Some unusual things I noticed during the boot process: - a message "doing fast boot" that looked unfamiliar; unfortunately it scrolled off too quickly to note its context
That message doesn't make it into dmesg. It's apparently a Suse thing, and perhaps normal, so let's ignore that for now.
- for each of the two SATA ports in use, a message "SATA port is slow to respond, please be patient" accompanied by about 10 secs wait
These messages seem to be a separate issue. I also get them with a .config that otherwise brings up the system successfully. That allowed me to capture a dmesg, so here are some possibly interesting hunks of the diff between a mainline kernel and a working 2.6.25-rc8-mm1 one: --- dmesg-2.6.25-rc8-git.nots-reordered 2008-04-09 15:29:52.000000000 +0200 +++ dmesg-2.6.25-rc8-mm1.nots 2008-04-09 00:48:42.000000000 +0200 @@ -1,4 +1,4 @@ - Linux version 2.6.25-rc8-testing-00210-g51ac03f (ts@xenon) (gcc version 4.2.1 (SUSE Linux)) #37 SMP PREEMPT Wed Apr 9 01:27:07 CEST 2008 + Linux version 2.6.25-rc8-mm1-testing (ts@xenon) (gcc version 4.2.1 (SUSE Linux)) #6 SMP PREEMPT Wed Apr 9 00:24:23 CEST 2008 BIOS-provided physical RAM map: BIOS-e820: 0000000000000000 - 000000000008f000 (usable) BIOS-e820: 000000000008f000 - 00000000000a0000 (reserved) [...] @@ -244,12 +277,10 @@ CPU1: Intel P4/Xeon Extended MCE MSRs (24) available CPU1: Thermal monitoring enabled CPU1: Intel(R) Pentium(R) D CPU 3.20GHz stepping 04 - Total of 2 processors activated (12796.06 BogoMIPS). + Total of 2 processors activated (12796.87 BogoMIPS).

Already, to get the diffs above I had to shift a few blocks of lines around.
Before I try booting that kernel again, any instructions on what to watch out for? Is netconsole usable again?Yes, netconsole is usable again ;)
Good to know. I'm now looking in my netconsole setup for the reason why I don't receive anything from it. Thanks, Tilman -- Tilman Schmidt E-Mail: tilman@xxxxxxx Bonn, Germany Diese Nachricht besteht zu 100% aus wiederverwerteten Bits. Ungeöffnet mindestens haltbar bis: (siehe Rückseite)
