[Bug 211511] suspend to RAM hangs on resume on Dell, regression between and -0.25

------- Comment #23 from jimc@xxxxxxxxxxxxx 2007-01-31 22:35 MST -------
First the bad news: init=/bin/bash is ineffective because /bin/bash has to be
read from the boot disc, whose module must therefore be loaded.
Now the good news: I hacked /init in the initrd for kernel 2.6.20-rc6 to
exec the initrd's copy of bash instead of starting udev, resulting in a system
on which no modules had ever been loaded, and enough function to test
suspending. (Note for people searching this archive: to create the new initrd,
search for "cpio" in /sbin/mkinitrd. In particular, cpio must have the "-H
newc" switch, otherwise the kernel will not recognize it as a initramfs and
will choke on it.)
Now more bad news: echo mem > /sys/power/state; the symptoms are identical
as before, i.e. suspends, but freezes solid upon resuming. This shows that
however wacko the SCSI subsystem may be, there is no fault in ata_piix or
scsi_mod or friends causing problems suspending.
Would the "beeping patch" help make any more progress? Do you have a URL
for this patch? Any other suggestions?
