I have a dmesg output from boot through suspend and it's subsequent
resume failure.
To answer some questions in earlier comments (although they were
directed at someone else):
- This lock up + disk I/O errors happens on every suspend/resume I've tried
which is about 4 times total in a few hours. All but the one for this
dmesg output are simply boot to the desktop, then suspend.
- The trace attached with this comment involves a hibernate and resume
before the suspend & resume. The hibernate and resume seemed to go
ok. I'd provide a cleaner trace, but getting any trace was tricky with
all
disk I/O reporting errors.
The attached dmesg trace comes from:
- Boot into Linux. Start Firefox.
- Hibernate to disk.
- Resume from disk. Seemed to go ok. Not very pretty though, but
it did resume back to the working Firefox, after presenting a
locked-screen
password dialog box.
- Switch away from the X login screen to a text console, to reduce the
chance
that suspend problems are due to video drivers. The NVidia driver is
loaded,
but similar looking suspend/resume problems have been seen after the
NVidia driver was uninstalled and the system restarted. So it does not
look like a likely cause.
- Login on the text console, and type "pm-suspend".
- It suspended ok, though a bit slowly. Windows suspended quite
slowly too.
- On resume, text console returned showing I/O error messages, eventually
ext4 remounted itself read-only, and generally doing anything was tough,
but the keyboard and console output did work.
- Used a USB flash key plugged in after resume and raw writing with dd to
capture the dmesg output.
- All the problems may be due to SATA I/O errors.
