This patch should fix multiple user-visible problems with the ACPI IRQ
routing after S3 resume:
"irq x: nobody cared"
"my interrupts are gone"
It probably applies to multiple bugzilla entries and mailing list posts.
Tested on my machine, which is experiencing similar problems. Seems to
work - although I get some non-fatal "nobody cared" messages that might
be caused by the i8042 driver.
Comments?
Stefan, can you test this?
Sorry for the very late reply.
I tested with 2.6.8.1(I think your patch it included there) with strange
results.
*It works fine if I unload ipw2100 before suspend and load it later
I can't find anything named "ipw2100" in my kernel source tree...
*In single user mode with ipw2100 loaded while S3, IRQ 11 is disabled on
resume, IRQ is not disabled
Huh? IRQ(what) is not disabled?
Please attach dmesg.
*When the system is fully booted up, everything seems to work fine.
What do you mean by this? If you suspend when more drivers are loaded,
things work fine, but don't work when less drivers are loaded?
I'll test a little bit more and report the results.
Thanks for testing.
Nathan
Cheers,
Stefan
