OpenSuse 11 eSATA failure with sata_sil24

[wfaust2]

After running OpenSuse 10.2+10.3 on my thinkpad T60 (T7200, latest BIOS) I did install OpenSuse 11.0.
Now the previously working eSata drives connected via a sil 3132 PCIExpress card do not work anymore.

After some access/time the drives (FreeAgent Pro, WD Studio,...) become inaccessable. Syslog reports:

Seems like something with the interupts is getting wrong? I tried different eSATA cards with different firmwares, but they are all sil3132 based and the bug shows up.

Question: does anybody has similar problems with eSATA cards and OpenSuse 11.0/2.6.25? Are there any eSATA PCIExpress cards for notebooks available here in Germany not based on sil3132 in hope that switching the controller will fix the problem?

Currently, it seems that both OpenSuse 10.3 and 11.0 have at least one kernel bug causing serious problems. I wonder, what bug the next kernel will fix and introduce new.

You can try to boot with "noapic" kernel parameter as a workaround until a (better) solution is found.
