Hi there, I am using Xen 3.0.3 testing and getting following error in domU while doing large copy: #time cp -R linux-2.6.18 linux-cp BUG: soft lockup detected on CPU#0! Pid: 998, comm: cp EIP: 0061:[<c0101227>] CPU: 0 EIP is at 0xc0101227 EFLAGS: 00000286 Not tainted (2.6.16.29-xen #52) EAX: 00000000 EBX: deadbeef ECX: deadbeef EDX: c056dc40 ESI: 0000055e EDI: bf874000 EBP: c7b6a000 DS: 007b ES: 007b CR0: 8005003b CR2: 08061494 CR3: 07204000 CR4: 00000640 [<c010693b>] sysxenentrynotifier+0x3b/0x50 [<c0104f8c>] syscall_call+0xa/0x16 sysxenentrynotifier is my function, which i call from system call handler to intercept system calls. I am also logging events inside xen and passing it to dom0 using shared memory setup between dom0 and Xen. When I copy events to dom0, I pause domU for sometime using function set_bit(VCPUF_blocked) and and then i un-pause it using clead_bit(VCPUF_blocked). Copy operation runs fine for sometime but after that domU gets hung and when I press any key in domU, it throws above mentioned error. If I try to perform the same operation but my logging code disabled, it works fine. Is it the problem related to my code or some Xen problem, which gets enabled when I pause or unpause domU. Any help or pointers in this regard would be very much appreciated. Thanks, Abhinav Unlimited freedom, unlimited storage.
