Distribution: Debian testing Hardware Environment: TP 600X Software Environment: Problem Description: I get the following errors/problems only with pre-emption enabled in the kernel: 1. pcmcia 'unable to remove socket power" errors (Bug #5061). Happens if full preemption is enabled ('low-latency desktop' as preemption model + PREEMPT_BKL), but not with mild preemption ('voluntary kernel preemption'). 2. S3 hangs upon going to sleep (Bug #5037). It happens regularly with full pre-emption, not with 'no forced preemption', and probably not with mild preemption (haven't been running that kernel for long enough to be sure). 3. errors like "os_wait_semaphore : Failed to acquire" (Bug #5008). Happens with full or mild preemption, but not with voluntary preemption. Steps to reproduce:

What's the status of this bug? Is (at least) part 1 of it resolved?
> 3. errors like "os_wait_semaphore : Failed to acquire" (Bug #5008). This part still happens with 2.6.15 (just started running it) with 'voluntary kernel preemption'. > 2. S3 hangs upon going to sleep (Bug #5037). With 2.6.15, I haven't seen this one using voluntary preemption, but I haven't tried full preemption ('low-latency desktop') yet. > 1. pcmcia 'unable to remove socket power" errors (Bug #5061). Also with 2.6.15, I haven't seen this one with voluntary preemption but I need to test full preemption. Daniel Ritz's patch reduced the problem a lot with 2.6.13 (I think that's what I was running then) with full preemption. At first I thought it had solved it, but then I it happened one more time. -Sanjoy `Never underestimate the evil of which men of power are capable.' --Bertrand Russell, _War Crimes in Vietnam_, chapter 1.
Any update on this problem? Thanks.
I'm closing this as fixed (all dependent bugs got closed AFAICS), please re-open it if you can still reproduce it.
