dmesg after disabling acpi_ec_burst_enable
I changed acpi_ec_burst_enable to printk and inconditionally return 0, but this
didn't solve the issue (see below my changes). See attached dmesg.

[Bug 9998] SCI interrupt storm - lost keystrokes - Acer Travelmate 4002
http://bugzilla.kernel.org/show_bug.cgi?id=9998 --- Comment #94 from Black brot.kann.man.nicht.einfrie...@gmail.com 2009-03-27 10:10:55 --- (In reply to comment #93) there was a change from msleep(1) to udelay(...) in drivers/acpi/ec.c among other things. If you could check that changing it back helps you, it will be great. Yes, it helps. Typing is fine, interrupts increase slowly. I found and changed udelay in 3 lines (2 in ec_poll, 1 in acpi_ec_transaction_unlocked). -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are on the CC list for the bug. -- ___ acpi-bugzilla mailing list acpi-bugzilla@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/acpi-bugzilla
