Re: 6.11.0 crash on X startup

[Bob Gill]

Addendum: I have a portion of /var/log/syslog of the 6.11-rc7 kernel, 
which contains a coredump, and

another line: Sep  8 20:13:06 freedom kernel: [  566.359456] ACPI: 
\_SB_.PCI0.SBRG.ASOC: Device cannot be configured due to a frequency 
mismatch

any takers?
