As far as I can see, the 2.6.19-rc ThinkPad situation is still 
confusing and we don't even know how many different bugs we are 
chasing...

Below is all the information I have found, plus some questions for the 
four people who reported problems that might hopefully bring us nearer 
to solutions.


Michael S. Tsirkin:
- ThinkPad T60 not coming out of suspend to RAM
- broken by commit cf4c6a2f27f5db810b69dcb1da7f194489e8ff88
  ("i386: Factor out common io apic routing entry access")
- question: Did the post -rc4 arch/i386/kernel/io_apic.c changes fix it?


Ernst Herzberg:
- ThinkPad R50p: boot fail with (lapic && on_battery)
- kernel compiled without cardbus support works
- question: Does reverting  the bisected
            commit 1fbbac4bcb03033d325c71fc7273aa0b9c1d9a03 
            ("serial_cs: convert multi-port table to quirk table")
            fix the problem?
- question: Does reverting commit cf4c6a2f27f5db810b69dcb1da7f194489e8ff88
            ("i386: Factor out common io apic routing entry access") help?
- question: If yes, did the post -rc4 arch/i386/kernel/io_apic.c changes
            fix it?


Hugh Dickins:
- ThinkPad T43p
- booting with "noapic nolapic" didn't make any difference
- reverting commit cf4c6a2f27f5db810b69dcb1da7f194489e8ff88
  ("i386: Factor out common io apic routing entry access") didn't help
- question: Was your bisecting successful?


Martin Lorenz:
- ThinkPad X60: lose ACPI events after suspend/resume
                not every time, but roughly 3 out of 4 times
- question: Does reverting commit cf4c6a2f27f5db810b69dcb1da7f194489e8ff88
            ("i386: Factor out common io apic routing entry access")
            in -rc4 help?
- question: If yes, did the post -rc4 arch/i386/kernel/io_apic.c changes
            fix it?

        of the darkness. There had been need of rain for many days.
       "Only a promise," Lao Er said.
