A few new problems cropped up with this kernel..
1. NFS seems to be unstable, oopsing when shutting down:

2. That message on the third line of the trace above: "kernel: Device not ready." is being logged every few mins or so, I believe it is my SCSI CDROM that is causing it. It also logs something similar after the SCSI driver has probed the device on boot:
Aug 20 12:24:36 tornado kernel: scsi0 : Adaptec AIC7XXX EISA/VLB/PCI SCSI HBA DRIVER, Rev 7.0 Aug 20 12:24:36 tornado kernel: <Adaptec 2940 Ultra SCSI adapter> Aug 20 12:24:36 tornado kernel: aic7880: Ultra Wide Channel A, SCSI Id=7, 16/253 SCBs Aug 20 12:24:36 tornado kernel: Aug 20 12:24:36 tornado kernel: Vendor: SONY Model: CD-RW CRX145S Rev: 1.0b Aug 20 12:24:36 tornado kernel: Type: CD-ROM ANSI SCSI revision: 04 Aug 20 12:24:36 tornado kernel: target0:0:6: Beginning Domain Validation Aug 20 12:24:36 tornado kernel: target0:0:6: Domain Validation skipping write tests Aug 20 12:24:36 tornado kernel: target0:0:6: FAST-10 SCSI 10.0 MB/s ST (100 ns, offset 15) Aug 20 12:24:36 tornado kernel: target0:0:6: Ending Domain Validation Aug 20 12:24:36 tornado kernel: Device not ready.
This has been a problem for quite a few weeks now, albeit I believe, only a cosmetic one.
3. As I have a Marvell Yukon 2 chipset, I was _delighted_ to see a new driver from Stephen Hemmingway appear in the netdev tree for it. However it seems to be a bit broken, I get link up and a bit of traffic before it just stops passing traffic of any sort and requires an rmmod/modprobe to get going again. I've emailed him directly about this.
4. PAM is complaining about "PAM audit_open() failed: Protocol not suppor ted" and I can't log in as any user including root. I would have picked this was a userspace problem, but it doesn't break with -rc5-mm1, yet reproduceably breaks with -rc6-mm1. Weird.
