With the latest stock Dapper kernel (2.6.15-20) I'm not seeing any "hdc: lost interrupt" messages nor does my shell become unresponsive after many (3+) suspend cycles.
I think I may have figured out what was causing my initial problem though. By unloading ohci1394 I'm able to resume from the second cycle and beyond. I noticed this when testing with the vanilla kernel. I initially thought it was fixed, but I only configured a kernel with minimal support. With full support I had the same problem. After a lot of experimenting, I narrowed it down to ohci1394. So, the DMA/CDROM seems to be working fine (I hope), and unloading/reloading ohci1394 doesn't seem to cause problems. I don't use firewire though so I can't really test it. -- enabling DMA on CD-ROMs causes hal failures https://launchpad.net/malone/bugs/22599 -- desktop-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
