I'm running the liveusb of the F11 beta release on a ThinkPad X200. On suspend and then resuming the laptop, I get this in the kernel log: usb-storage: device scan complete scsi 5:0:0:0: Direct-Access USB2.0 CardReader SD0 0100 PQ: 0 ANSI: 0 sd 5:0:0:0: [sdc] 4022272 512-byte hardware sectors: (2.05 GB/1.91 GiB) sd 5:0:0:0: [sdc] Write Protect is off sd 5:0:0:0: [sdc] Mode Sense: 03 00 00 00 sd 5:0:0:0: [sdc] Assuming drive cache: write through sd 5:0:0:0: [sdc] 4022272 512-byte hardware sectors: (2.05 GB/1.91 GiB) sd 5:0:0:0: [sdc] Write Protect is off sd 5:0:0:0: [sdc] Mode Sense: 03 00 00 00 sd 5:0:0:0: [sdc] Assuming drive cache: write through sdc: sdc1 sd 5:0:0:0: [sdc] Attached SCSI removable disk sd 5:0:0:0: Attached scsi generic sg1 type 0 e1000e: eth0 NIC Link is Up 100 Mbps Full Duplex, Flow Control: None 0000:00:19.0: eth0: 10/100 speed: disabling TSO SELinux: initialized (dev sdc1, type vfat), uses genfs_contexts SQUASHFS error: squashfs_read_data failed to read block 0x186ee31e SQUASHFS error: Unable to read data cache entry [186ee31e] SQUASHFS error: Unable to read page, block 186ee31e, size 8d88 SQUASHFS error: Unable to read data cache entry [186ee31e] SQUASHFS error: Unable to read page, block 186ee31e, size 8d88 EXT4-fs error (device dm-0): ext4_find_entry: reading directory #38841 offset 0
Additionally, minefield (firefox) starts crashing in a while and then the system stops responding in some time. Further messages in the kernel log: SQUASHFS error: squashfs_read_data failed to read block 0x7447361 SQUASHFS error: Unable to read data cache entry [7447361] SQUASHFS error: Unable to read page, block 7447361, size aaff SQUASHFS error: Unable to read data cache entry [7447361] SQUASHFS error: Unable to read page, block 7447361, size aaff ...

Further info: just when all apps start to crash, this is the output from dmesg|tail (the only thing that seems to work): Buffer I/O error on device dm-0, logical block 0 lost page write due to I/O error on dm-0 EXT4-fs error (device dm-0): ext4_find_entry: reading directory #37630 offset 0 EXT4-fs: previous I/O error to superblock detected for dm-0 Buffer I/O error on device dm-0, logical block 0 lost page write due to I/O error on ddm-0 ... After this, the gnome panels go away; switching to a VT works but login doesn't work. I can switch back to the desktop but there's no response to keystrokes or clicks.
These look devicemapper IO errors; ext4 & squashfs messages are just reporting the IO error. Where'd DM go? I'll stay on cc: but I don't think this is a filesystem bug. Doing more than just "dmesg | tail" but instead looking at all of dmesg after you resume may offer more clues.... Another idea; did the usb stick come back as a different device after resume? What does dm-0 think its physical volume is?
I agree it's not a fs bug. Yes, the usb disk gets detected as a new one; a popup appears that asks me to mount it, browse photos, etc. (as far as I remember). As my orig dmesg output in the 1st comment shows, the usb device is redetected and added.
This bug appears to have been reported against 'rawhide' during the Fedora 11 development cycle. Changing version to '11'. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
I have the same problem (ext4 errors) with the root ext4 filesystem of a f11 install. Unfortunately, I wasn't able to produce any logs since the system is unusable after resume.
This message is a reminder that Fedora 11 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 11. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '11'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 11's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 11 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Fedora 11 changed to end-of-life (EOL) status on 2010-06-25. Fedora 11 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
