Bug Description
SRU justification:
Impact: Updates from the 2.6.27.12 enabled the isp1761 module implicitly, triggering a bug in the probe function as a side effect. This causes a kernel oops at boot on machines with that hw.
Fix: Patch from upstream (2.6.28rc2, so Jaunty is not affected) which fixes the probing code. Updated kernel has been verified to solve the problem. Changes a limited to that specific driver.
Testcase: Boot with affected hw (see report).
I'm running into a regression between 2.6.27-9 and 2.6.29-11 where loading the isp1760 driver during bootup causes a kernel oops in isp1761_pci_probe. This prevents my laptop from continuing to boot up.
Adding "blacklist isp1761" to my /etc/modprobe.

This seems to be related to the isp1760 module suddenly coming into existence. It was not built in -9, and with this commit[1], it got turned on.
