ACPI panic on Fujitsu-Siemens C6175

Hi,

With ACPI enabled, I get the following panic scenario.  This only happens
in multi-user mode, on a Fujitsu Siemens C6175.  BIOS revision 1.31
(latest).  On a 5.2.1 system, it worked correctly.

#zzz
(when using APM instead of ACPI this gives a
"ioctl(APMIO_SUSPEND): invalid argument" message)
<suspend>
<hit resume button>
<resume>

I then get these kernel messages: (N,x,y,z vary)
---

 db> panic
Dumping 191MB
Dump failed writing header (5)
---
The "dump failed" message is strange, as 191MB should fit on a 384MB
swap partition.

Could this be usb-related? usbd was still running when I suspended the
laptop.

I also get some error messages from the AML compiler when trying to
compile the AML code from acpidump -d
