Can you please > point us to the patch which fixes this issue? To be honest, I actually don't know which patch fixed the issue. I saw the problem during some early testing of the latest PM branch, and in the process of restructuring the tree it went away. More than likely, I had left out part of the series when reorganizing that caused this temporary problem. I think I'll remove it from the 'known problems' list as it appears to have been operator error on my part.

Kevin, I did some testing with the current PM branch and don't see this issue on SDP. I could not find the patch which fixes this issue. Can you please point us to the patch which fixes this issue?

- Original Message - From: "Kevin Hilman" Known problems: - network drivers and off-mode - various hangs when using off-while-idle and NFS-mounted rootfs - network drivers likely need some context save/restore support Kevin, was this known to work earlier. Could this be related to GPMC context save/restore.

PM branch update: rebase to .31-rc, added omap_hwmod/omap_device
The PM branch hosted in my linux-omap-pm repo[1] has been updated. Significant changes: - rebased to omap/master (currently v2.6.31-rc1) - Using new omap_hwmod and omap_device infrastructure from Paul Walmsley - more reorg into groups of commits for easier submission upstream Tested on the following platforms using omap3_pm_defconfig with busybox-based initramfs, and tested full-chip RET and OFF in idle and suspend: - 3430SDP - OMAP3EVM - Beagle - Overo - RX51 - Zoom2 (use 'pm-staging/zoom2' branch as well, which is Vikram's zoom2 branch rebased on top of PM branch with DEBUG_LL support and misc. fixes) Known problems: - no DVFS because of next item... - SRF driver broken, needs update for new hwmod/omap_device layer (default config used PM NOOP) - network drivers and off-mode - various hangs when using off-while-idle and NFS-mounted rootfs - network drivers likely need some context save/restore support - SDRAM on 2 CSes (Beagle, Overo, RX51) - need to boot with mem=128M so only a single CS is used - 2 CS support patches from Jean Pihet solve this problem, but not yet merged. - 3430SDP ES3.0 - UART1 doesn't come back from off-while-idle (ok on es3.1 SDP) [1] http://git.kernel.org/?p=linux/kernel/git/khilman/linux-omap-pm.git -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
