| |
I just started testing the cPCI hotplug driver I'm working on against 2.4.19 after upgrading the kernel in SOMA's in-house distribution, and I'm now getting the attached oops code when trying to access the pcihpfs (e.g. with ls) after mounting it. I backed out the couple of changes I made last night that might have been remotely connected (added hardware_test and get_power_status hotplug ops in my driver), and I'm still getting it in the same place, so it looks like maybe a VFS change somewhere in 2.4.19 broke pcihpfs. Any ideas?
Thanks,
Scott
